📡 THE SIGNAL — What Happened
Why it matters: In early 2026, Russia's deployment of new weapons to the Ukrainian front further dimmed prospects for an end to the war, structurally transforming the security environment across Northeast Asia, including Japan. This move is not merely a tactical escalation but could be a turning point accelerating the reorganization of the post-Cold War international order itself.
- Military — Russia deployed new weapon systems to the Ukrainian front in early 2026. Reports indicate the combat deployment of a ground-launched modified version of the hypersonic missile "Tsirkon" and AI-guided drone swarms.
- Military — The war in Ukraine entered its fourth year since the full-scale invasion began in February 2022, with cumulative casualties on both sides estimated to exceed 500,000.

- Energy — Europe's reliance on Russian natural gas decreased from approximately 40% in 2021 to about 15% in 2025, but rising alternative energy costs are straining economies.
- Diplomacy — In February 2026, Turkey again attempted mediation, but Russia effectively rejected negotiations, citing the recognition of "territorial realities" as a precondition.
- Society — Displaced persons from Ukraine have reached approximately 6.3 million across Europe, and the social and financial burden on host countries is becoming a political issue.
- Military — The Russian military intensified its offensive in the Donbas region using new weapons, reportedly occupying approximately 120 square kilometers of new territory in the two months of January-February 2026.
To understand the phenomena of the prolonged war in Ukraine and the deployment of new weapons, it is necessary to survey the structural changes over more than 30 years since the end of the Cold War.
After the collapse of the Soviet Union in 1991, NATO gradually expanded eastward, successively incorporating countries from the former Soviet bloc. In 1999, Poland, the Czech Republic, and Hungary joined, and in 2004, seven countries, including the Baltic states, joined simultaneously. Russia consistently viewed this expansion as a security threat, but due to economic vulnerability, it lacked effective countermeasures from the Yeltsin era to the early Putin administration.
The turning point came with the 2008 Georgian War. Russia demonstrated its ability to alter the status quo by military force, and the limited Western response deepened its conviction in shaping order through power. The 2014 annexation of Crimea was an extension of this, showcasing a new form of warfare: hybrid warfare. While Western nations responded with economic sanctions, they refrained from military intervention, effectively signaling to Russia that "costs were manageable."
The full-scale invasion of Ukraine in February 2022 was the culmination of this gradual escalation. However, contrary to Russia's initial assumptions, Ukrainian resistance was fierce, and Western unity proved stronger than expected. The war shifted from a quick decisive battle to a war of attrition, with a stalemate reminiscent of World War I trench warfare persisting.
The deployment of new weapons in early 2026 reflects Russia's strategic decision to break this stalemate. The combat deployment of hypersonic weapons and AI-guided drone swarms signifies a new stage in the technological arms race. Particularly noteworthy is that these weapon systems are the result of military-technical cooperation with Iran and North Korea. Russia, under sanctions, is deepening its ties with other countries that oppose the West, effectively forming an "anti-Western military-technical alliance."
For Japan, this development has direct security implications. North Korea's acquisition of missile technology and combat experience through cooperation with Russia increases the risk of a contingency on the Korean Peninsula. Furthermore, Russia's maintenance and strengthening of its military posture in the Far East further rigidifies Japan-Russia relations, including the Northern Territories issue. The large-scale military exercise conducted by Russia in the Kuril Islands (Chishima Islands) in December 2025 was a symbolic event.
In a broader context, the prolongation of the war in Ukraine serves as a litmus test for the international community's ability to respond to "unilateral changes to the status quo by force." If Russia succeeds in solidifying its military gains, there is a risk of inciting China's actions in the Taiwan Strait and the South China Sea. What Japanese security policymakers are most concerned about is precisely this "precedent effect," and the significant increase in defense spending and the development of counterattack capabilities since 2023 directly reflect the lessons learned from Ukraine.
Historically, wars of attrition between great powers often lead to "war fatigue" and "frozen conflicts." The Korean War (1950-53) was frozen by an armistice agreement and technically continues more than 70 years later. The war in Ukraine is increasingly likely to follow a similar trajectory, in which case the security environments of Europe and Asia would revert to a divided structure similar to the Cold War era. This structural shift is the most significant dynamic behind individual tactical news.
The delta: The combat deployment of new Russian weapons (modified hypersonic missiles, AI-guided drone swarms) is not merely a tactical change but a strategic turning point demonstrating the operationalization of an "anti-Western military-technical alliance" between Russia, Iran, and North Korea. This development makes the war in Ukraine a linked factor directly transforming the security environment not only in Europe but also in Northeast Asia, pushing Japan's defense policy into a new phase of simultaneously addressing three-front threats (Russia, China, North Korea).
🔍 BETWEEN THE LINES — What the Reports Aren't Saying
While official reports treat "new weapon deployment" as a tactical-level issue, the essential change lies in the irreversible integration of military technology among Russia, Iran, and North Korea. What Japanese defense authorities are most concerned about is not merely North Korea supplying ammunition to Russia, but the establishment of a cycle where North Korea gains hypersonic technology and electronic warfare know-how by using the Ukrainian battlefield as a "testing ground," and then applies this back to its missile capabilities against Japan. The true driving force behind the Ministry of Defense's budget increase is the acceleration of this "triangular technology transfer," rather than the Russian threat itself.
NOW PATTERN
Spiral of Conflict × Alliance Fissures × Overstretch of Power
Russia's deployment of new weapons accelerates the "spiral of conflict" in the war in Ukraine, simultaneously increasing the risk of "overstretch of power" for both the anti-Western bloc and Western alliances, while testing "fissures" within alliances.
Intersection of Dynamics
The three dynamics of "spiral of conflict," "alliance fissures," and "overstretch of power" form a dangerous complex system that mutually reinforces itself. The more the spiral of conflict escalates, the greater the economic and military burden on each bloc, increasing the risk of overstretch of power. As the pressure of overstretch intensifies, friction over burden-sharing within alliances escalates, and fissures expand. And if alliance fissures become apparent, the opposing side perceives this as an opportunity to escalate further, accelerating the spiral.
Within this complex dynamic, Japan is in a particularly vulnerable position. Geographically surrounded by three nuclear-armed states (including de facto ones)—Russia, China, and North Korea—Japan simultaneously experiences the effects of each dynamic brought about by the prolonged war in Ukraine. The spiral of conflict poses a direct threat through North Korea's improved missile capabilities, alliance fissures create anxiety about the reliability of the Japan-U.S. alliance, and the overstretch of power manifests as fiscal pressure due to Japan's own increased defense spending.
Furthermore, it is crucial that these three dynamics have different effects on the variable of "time." The spiral of conflict is most visible in the short term, appearing as new weapon deployments and front-line changes. Alliance fissures emerge in the medium term, manifesting as policy discontinuities through electoral cycles and changes in government. The overstretch of power is most decisive in the long term, altering the relative positions of great powers over a 10- to 20-year span. The challenge for policymakers is to integrally understand these dynamics operating on different time axes and to simultaneously manage short-term crises and build long-term strategies. The current international environment, where these three dynamics operate simultaneously with high intensity, forms the most complex security environment since the Cold War.
📚 PATTERN HISTORY
1950-1953: Korean War
Proxy war between great powers stalemates, becoming a frozen conflict
Structural similarities with the present: US-Soviet nuclear deterrence prevented an all-out war, but the armistice line remains unchanged after more than 70 years. The introduction of new weapons (MiG-15 vs. F-86) brought tactical equilibrium but did not lead to a strategic resolution. In Ukraine, new weapons are also highly likely to prolong the stalemate.
1979-1989: Soviet Invasion of Afghanistan
Military overstretch by a great power accelerates national decline
Structural similarities with the present: A decade-long war of attrition hastened the economic and political collapse of the Soviet Union. The US supply of Stinger missiles changed the tide of the war, but pushing the Soviet Union too far created a new risk of destabilizing a nuclear power. Russia's overstretch could lead to a similar outcome.
1980-1988: Iran-Iraq War
Deployment of new weapons in a war of attrition prolongs the conflict and draws in third countries
Structural similarities with the present: Gradual escalation including the use of chemical weapons, the Tanker War, and Iranian missile attacks. External arms supplies (US support for Iraq, China/North Korea support for Iran) prolonged the war for eight years. This bears a strong structural resemblance to current North Korean and Iranian support for Russia.
2001-2021: US War in Afghanistan
Proof that technological superiority does not guarantee sustained victory
Structural similarities with the present: The US, possessing the world's most advanced military technology, withdrew after 20 years of war. Technological superiority, such as drones and GPS-guided bombs, brought tactical victories, but military operations without a political solution ultimately proved unsustainable. The lesson that technology alone cannot win a war also applies to Russia's deployment of new weapons.
2014-Present: Continuation from the Eastern Ukraine Conflict (Donbas War)
When frozen conflicts thaw, they escalate into larger wars
Structural similarities with the present: The "freezing" of the 2014 annexation of Crimea and the Donbas conflict did not prevent the full-scale invasion in 2022. Rather, during the frozen period, Russia rebuilt its military capabilities and prepared for a larger attack. A "frozen" scenario in current ceasefire negotiations could also sow the seeds for future re-escalation.
Patterns Revealed by History
The most important pattern revealed by historical precedents is the paradox that the deployment of new weapons in wars of attrition between great powers prolongs, rather than shortens, the conflict. In all cases—jet fighters in the Korean War, chemical weapons in the Iran-Iraq War, drones in Afghanistan—technological superiority brought temporary tactical effects but induced adaptation and countermeasures from the opposing side, ultimately prolonging the stalemate.
Furthermore, the historical pattern that military overstretch by great powers ultimately leads to the structural decline of national power is clear. In the cases of the Soviet Union in Afghanistan and the United States in Vietnam and Afghanistan, the expansion of military commitments exposed the limits of economic and political sustainability. While Russia currently maintains military spending at 6.5% of GDP, it is highly questionable whether this is sustainable for 5 or 10 years.
Moreover, the pattern that "frozen conflicts" become breeding grounds for future large-scale conflicts is the most cautionary lesson for Ukraine. The lessons of 2014 show that an incomplete ceasefire invites further escalation, and history repeatedly proves that any form of war termination will not bring lasting peace without effective security mechanisms to prevent recurrence.
🔮 WHAT'S NEXT
The war in Ukraine will not end in 2026, and a "hot stalemate" will continue. Russia's new weapons will bring localized tactical advantages, but Ukraine will restore equilibrium through the supply of counter-weapons from the West (more advanced air defense systems, electronic warfare equipment, AI defense systems). The front lines will not shift significantly, and a war of attrition will persist, with both sides contesting territory measured in tens of square kilometers annually.
Diplomatically, Turkey, China, India, and others will intermittently attempt mediation, but the gap between the minimum conditions of both sides (Russia's recognition of occupied territories, Ukraine's restoration of pre-2022 borders) will be too wide for substantive negotiations. A partial ceasefire (cessation of hostilities in specific areas) might be explored in the latter half of 2026, but a comprehensive peace agreement remains distant.
For Japan, pressure for further increases in defense spending will continue, with the FY2027 budget expected to reach the 9 trillion yen range. North Korea will repeatedly launch missiles based on technology acquired through cooperation with Russia, continuously challenging the effectiveness of Japan's missile defense system. Economically, persistently high energy prices and sanctions-related supply chain disruptions will continue, exerting downward pressure of approximately 0.3-0.5% of annual GDP on the Japanese economy.
Implications for Investment/Action: Continued front-line stalemate, repeated formal resumption and breakdown of diplomatic negotiations, gradual expansion of Western aid, continued Russian mobilization
A ceasefire or armistice of some form will be achieved in 2026. The most probable scenario is one where Russia's economic exhaustion progresses more than anticipated, and the Putin regime accepts a ceasefire under minimal conditions that can be declared a "victory" domestically. Specifically, this could involve establishing a ceasefire line that tacitly acknowledges Russia's de facto control over areas it effectively occupies (Crimean Peninsula, most of Donetsk and Luhansk Oblasts, parts of Zaporizhzhia and Kherson Oblasts).
Conditions for this scenario to materialize include one or a combination of the following factors: (1) Russia's domestic inflation rate exceeds 20% annually, and social discontent reaches a critical point; (2) China reduces economic support to Russia and urges the Putin regime to accept a ceasefire; (3) The United States, under a new administration, offers direct security guarantees to Ukraine, inducing concessions from the Ukrainian side.
In this case, positive impacts for Japan would include stabilization of energy prices, economic benefits from reduced international tensions, and renewed international pressure on North Korea. However, the risk of recurrence of a "frozen conflict" would remain, and the necessity for defense buildup would not change.
Implications for Investment/Action: Rapid deterioration of Russian domestic economic indicators, clear shift in China's policy towards Russia, activation of secret negotiation channels between the US and Russia, groundwork for Putin's domestic "victory declaration"
The war escalates further, with Russia engaging in direct provocative actions against NATO member states (normalization of airspace violations over the Baltic states, destruction of undersea cables, large-scale cyberattacks), leading to discussions about invoking NATO Article 5 (collective defense clause). Alternatively, escalation progresses to a level where Russia hints at the use of tactical nuclear weapons.
Triggers for this scenario could be one of the following: (1) Ukrainian forces launch a full-scale attack on the Crimean Peninsula, which Russia perceives as an "existential threat"; (2) A political upheaval occurs in Russia, and a more hardline leader seizes power; (3) North Korea deploys a large contingent of troops to Ukraine based on an agreement with Russia, leading to the internationalization of the war.
The impact on Japan would be severe and direct. If a direct confrontation between NATO and Russia materializes, an inevitable shift of US forces from the Indo-Pacific would occur, compelling Japan to urgently strengthen its own deterrence capabilities. If nuclear threats become normalized, discussions on nuclear sharing within Japan could intensify. Economically, a sharp rise in global security premiums, soaring energy prices, and severe supply chain disruptions would occur, putting the Japanese economy at risk of recession.
Implications for Investment/Action: Increased frequency and intensity of Russian provocative actions against NATO member states, hints at changes to nuclear doctrine, signs of large-scale North Korean troop deployment, significant reinforcement of NATO forces in Eastern Europe
