To understand former Special Envoy Kellogg's statement that "a ceasefire depends on Putin," it is necessary to delve deeply into the structural background of the Ukraine conflict and the evolution of Russia's foreign policy over the past 30 years.
In the 1990s, after the end of the Cold War, Russia faced the dual shock of a rapid decline in national power due to the collapse of the Soviet Union and NATO's eastward expansion. The accession of Poland, the Czech Republic, and Hungary to NATO in 1999, and the large-scale eastward expansion in 2004, including the Baltic states, appeared to Moscow as a "breach of promise." President Putin sharply criticized the West's "unipolar dominance" at the 2007 Munich Security Conference, and this speech became the starting point for the current confrontational structure.
The 2008 Georgian War, the 2014 annexation of Crimea, and the Donbas conflict clearly demonstrated Putin's willingness to alter the status quo by military force. However, the international community's response was limited, which gave Putin the mistaken conviction that "the costs of military adventures are manageable." This is the structure of so-called "moral hazard." The full-scale invasion in February 2022 was an extension of this conviction.
However, the invasion did not proceed as initially expected. The Russian army failed to capture Kyiv, and the front lines became static in the east and south. Large-scale Western military aid, particularly the provision of HIMARS and Patriot missiles, significantly enhanced Ukraine's defensive capabilities. Although Ukraine's counteroffensive in 2023 did not achieve the anticipated results, Russian military losses were substantial.
President Trump, who took office in January 2025, pledged a "ceasefire within 24 hours." However, this pledge was not realized, and Special Envoy Kellogg was tasked with peace negotiations. Kellogg, a retired Army Lieutenant General who served as Acting National Security Advisor during the first Trump administration, held a relatively hawkish stance. Yet, despite his negotiation efforts, President Putin continued to reject ceasefire proposals that included territorial concessions.
What is crucial here are the structural reasons why Putin refuses a ceasefire. Firstly, there are domestic political dynamics in Russia. Putin has positioned the "special military operation" as a battle for national survival, and a withdrawal without a clear "victory" would fundamentally undermine the legitimacy of his regime. Secondly, the Russian economy has shown some resilience despite sanctions. Trade with countries like China, India, and Turkey has filled the gaps created by sanctions, and energy exports have not completely ceased. Russia's GDP in 2025 decreased by approximately 10% compared to pre-sanction levels, but it has not collapsed. Thirdly, "aid fatigue" in the West gives Putin the calculation that time is on his side.
Kellogg's resignation and this NHK interview symbolize this structural stalemate. For a US negotiator to state that "it depends on Putin" effectively means that the US has relinquished leadership in negotiations and entrusted the issue to Russia's decision-making. This exposes the limits of the Trump administration's "deal diplomacy" and simultaneously suggests a retreat of the US's role as an arbiter in the international order.
Historically, ceasefires in great power conflicts have been achieved either when one side clearly wins or when both sides are exhausted and a "ripe moment" arrives. The Korean War concluded with an armistice after three years of stalemate, and the Iran-Iraq War ended in a ceasefire after eight years of attrition. The current Ukraine conflict has not yet met either of these conditions. Putin is convinced of "victory," and Ukraine cannot make concessions as it faces an existential crisis. This structural stalemate is the fundamental issue underlying Kellogg's statement.
The delta: Former Special Envoy Kellogg's statement that "a ceasefire depends on Putin" effectively acknowledges that the Trump administration's "deal diplomacy" has failed in the Ukraine issue, indicating a structural turning point where the US's negotiation leadership has shifted to Russia.
🔍 Between the Lines — What the News Isn't Saying
The true reason Kellogg gave an interview to NHK at this timing is to record the failure of the Trump administration's negotiation approach as "Putin's fault" before his own resignation. For a retired envoy to publicly state "it depends on the other side" is highly unusual in diplomacy and serves as a preemptive defense in domestic US policy debates. Furthermore, it is noteworthy that this statement suggests a rapid decline in the priority of the Ukraine issue within the Trump administration. The message, effectively "we've done what we can," should be read as a precursor to future reductions in US involvement.
NOW PATTERN
Overextension of Power × Spiral of Conflict × Failure of Cooperation
Putin's military overextension structurally impedes a ceasefire, while the spiral of conflict between the US and Russia and the failure of international cooperation solidify the stalemate.
Intersection of Dynamics
The three dynamics of "Overextension of Power," "Spiral of Conflict," and "Failure of Cooperation" form a mutually reinforcing vicious cycle. This interaction is the core mechanism explaining the stalemate in the Ukraine conflict.
Firstly, Putin's overextension of power has created a structure from which he cannot withdraw. Politically, needing a "victory" domestically, Putin cannot accept reasonable compromise. This rigidity acts as an escalation engine for the spiral of conflict. Because Putin cannot compromise, the West is forced to strengthen sanctions and military aid, to which Russia responds with further escalation.
Secondly, this spiral of conflict deepens the failure of international cooperation. As escalation progresses, the interests of various nations become intricately intertwined, making it difficult to maintain a unified stance. Political divisions within the US, the issue of burden-sharing in Europe, and the neutral stance of the Global South are all byproducts of the spiral of conflict.
Thirdly, the failure of cooperation maintains the conditions that enable Putin's overextension. If the international community cannot collectively pressure Russia, Putin has no need to change his calculation that "he can win a war of attrition." In other words, a triple vicious cycle is formed where the failure of cooperation enables the persistence of overextension, overextension drives the spiral of conflict, and the spiral deepens the failure of cooperation.
Kellogg's statement can be read as a frank admission that American diplomacy has faced structural limits within this vicious cycle. "It depends on Putin" is a euphemism for the lack of external means to break this vicious cycle, and also an expression of the international community's powerlessness. To break this structure, an exogenous shock must be applied to one of the three dynamics—for example, political change within Russia (collapse of overextension of power), a decisive military turning point (disruption of the spiral of conflict), or active mediation by China (overcoming the failure of cooperation)—but the prospects for any of these to materialize in the short term are slim.
📚 Pattern History
1950-1953: Stalemate and Armistice in the Korean War
A proxy war between great powers fell into military stalemate, and an armistice was achieved due to an exogenous shock: the death of one leader (Stalin).
Structural similarity with the present: Structural stalemates are often broken not by rational calculations of the parties involved, but by exogenous shifts in power.
1979-1989: Soviet Invasion and Withdrawal from Afghanistan
Initial military success transformed into a long-term war of attrition. Withdrawal was linked to domestic political system changes (Gorbachev's reforms).
Structural similarity with the present: Withdrawal from overextension of power requires a change in leadership or fundamental domestic regime change.
1980-1988: Iran-Iraq War
Both sides continued the war, convinced of victory, and a ceasefire based on a UN resolution was achieved after eight years of attrition.
Structural similarity with the present: When "mutual exhaustion" of both sides is a prerequisite for a ceasefire, peace may be delayed but will eventually arrive.
2008: Russia-Georgia War and the International Community's Response
The limited Western response to Russia's military actions led to future escalation (annexation of Crimea).
Structural similarity with the present: Insufficient response due to failure of cooperation sends a false signal to aggressors that "costs are manageable," leading to larger conflicts.
2014-2015: Annexation of Crimea and Minsk Agreements
After military faits accomplis, "frozen conflicts" are formed, where diplomatic solutions nominally continue but are practically ineffective.
Structural similarity with the present: Incomplete ceasefire agreements "freeze" conflicts but do not resolve them, becoming seeds for future, larger clashes.
Patterns Shown by History
The most important lesson shown by historical patterns is that structural stalemates caused by a great power's military overextension are extremely rarely resolved through rational negotiations between the parties involved. The Korean War ended with Stalin's death, and the Afghan War with the transformation of the Soviet system, both exogenous shocks. The Iran-Iraq War only achieved a ceasefire after eight years of attrition.
These historical precedents suggest a pessimistic outlook for a short-term resolution to the Ukraine conflict. As long as Putin's power base remains stable and the Russian economy does not completely collapse, the "structural stalemate" is likely to continue. Kellogg's statement, "it depends on Putin," can be seen as an intuitive grasp of this historical pattern. History repeatedly shows that achieving a ceasefire requires one of several exogenous shocks—a change in leadership, regime transformation, or complete exhaustion of both sides. In the current situation, the prospects for any of these conditions to be met in the short term are low, making a prolonged conflict the most probable scenario.
🔮 Next Scenarios
The Ukraine conflict will continue in a military stalemate throughout 2026, with no ceasefire achieved. President Putin will not make substantial concessions due to domestic political constraints, and the eastern Ukraine front will see minor skirmishes but no major shifts. The Trump administration will gradually reduce its involvement in the Ukraine issue, demanding greater burden-sharing from Europe. Western sanctions will remain, but their effectiveness will gradually diminish due to circumvention trade via China, India, Turkey, and other countries.
European nations will explore frameworks for security commitments to Ukraine but will not extend NATO's direct security umbrella. Ukraine's economic exhaustion will deepen, and while reconstruction discussions will proceed, concrete funding will stagnate. The Russian economy will also see slowed growth due to the pressure of military spending but will not experience a rapid collapse. This "frozen conflict" situation will resemble the Donbas situation after the 2014 Minsk Agreements, but with significantly greater scale and impact. The international community's attention will gradually shift to other issues (Taiwan Strait, Middle East), and the Ukraine issue will become fixed as a "managed crisis."
Implications for Investment/Action: Frontline stabilization, decrease in offensive tempo from both sides, reduction in Ukraine-related statements from the Trump administration, increased discussion of a unique European security framework
Ceasefire negotiations will make substantial progress due to some exogenous shock. The most likely scenario is one triggered by a change in the power dynamics within the Putin regime or a rapid deterioration of the Russian economy. The cumulative effect of sanctions and increased Russian military spending could strain finances, potentially leading to a full-blown recession in the Russian economy in late 2026. This could destabilize Putin's domestic support base, creating political space for a ceasefire.
Alternatively, China might begin to play a more active role as a mediator. If the Xi Jinping administration determines that Russia's long-term attrition is detrimental to China's strategic interests, it could exert stronger pressure on Putin. In this case, a ceasefire framework backed by Chinese influence might be formed, potentially leading to a "provisional ceasefire" that shelves territorial issues.
Furthermore, a decisive military turning point on the battlefield—for example, Ukraine's recapture of important strategic locations through a new counteroffensive—could also change Putin's calculations. In any case, a ceasefire would likely mean a "freeze" of the conflict rather than a final resolution.
Implications for Investment/Action: Rapid deterioration of Russian economic indicators, personnel changes within the Putin administration, China's diplomatic initiatives, significant battlefield advances by Ukraine
The conflict escalates further, making a ceasefire even more distant. The most concerning scenario is the heightened threat of nuclear escalation if Russia is cornered. Should Putin hint at the use of tactical nuclear weapons or conduct a nuclear test, the international community would face an unprecedented crisis.
Additionally, the Trump administration might decide to significantly cut aid to Ukraine. If congressional budget approval stalls and military aid ceases, Russian forces could attempt broader advances in eastern Ukraine. This carries the risk of Ukraine's defense lines collapsing and larger territorial losses occurring.
Furthermore, the risk of the conflict expanding beyond Ukraine's borders cannot be ruled out. Increased Russian airspace violations or cyberattacks against NATO member states (especially the Baltic states and Poland), or intervention in Moldova's Transnistria, could trigger a crisis over the activation of NATO Article 5. The deployment of additional forces from North Korea and the expansion of Iran's military technology assistance are also risk factors that could bring about a qualitative change in the conflict.
Implications for Investment/Action: Unusual movements regarding Russia's nuclear forces, rejection of Ukraine aid budget in US Congress, increased Russian provocations against NATO member states, expansion of North Korea and Iran's military cooperation with Russia
