Institute for the Study of War: Kremlin demands a veto over western security guarantees for Ukraine

Institute for the Study of War

The Kremlin is demanding that Russia have a veto over any Western security guarantees for Ukraine in an effort to undermine ongoing US, European, and Ukrainian efforts to establish conditions for lasting peace in Ukraine. Russian Foreign Minister Sergey Lavrov stated on August 20 that any serious discussions on Western security guarantees for Ukraine without Russian input are a “road to nowhere” and that Russia “cannot agree” that now-proposed “collective security issues” can be resolved without Russia, effectively demanding a Russian veto over Western security guarantees for Ukraine.[1] Lavrov also threatened that Russia will take “firm and harsh” action to ensure that Russia’s “legitimate interests” are a part of any postwar security arrangement for Ukraine.

The Kremlin is likely trying to inject its demands into the ongoing US, European, and Ukrainian joint effort to create a security structure that will serve as a safeguard against a future Russian re-invasion in the event of a peace settlement.[2] Granting Russia veto power over Western security guarantees would enable the Kremlin to dictate conditions that will weaken Ukraine’s ability to resist another Russian invasion by preventing Ukraine from forming binding bilateral or multilateral security agreements such as are now being discussed, increasing and modernizing its military, and receiving support from Ukraine’s partners. Russian Foreign Affairs Ministry Spokesperson Maria Zakharova recently said that Russia could not tolerate the presence of troops from NATO member states in Ukraine as part of any security guarantees.[3]

European leaders recently released a joint statement reaffirming that no peace agreement should place limitations on Ukraine’s armed forces or on its cooperation with third countries nor can Russia have veto power over Ukraine’s pathway to joining the European Union (EU) or NATO.[4] European Commission Vice President Kaja Kallas stated on August 19 that Russian President Vladimir Putin cannot be trusted to honor any promises or commitments to permanently cease military activity against Ukraine and that any security guarantees must be robust and credible to deter the Russian military command does not re-group and launch a future invasion of Ukraine.

The Kremlin appears to be demanding that any security guarantees be based on those proposed in the Istanbul 2022 framework, which would grant Russia and its allies the right to veto Western military assistance to Ukraine and leave Ukraine helpless in the face of future Russian threats. Lavrov stated on August 20 that Russia is in favor of collective security guarantees that are “truly reliable” and that a good example of such guarantees was evident in the 2022 Istanbul Ukraine-Russia negotiations, which would have permanently prohibited Ukraine from joining NATO, imposed limitations on the Ukrainian military, and banned Ukraine from receiving Western military assistance without any imposing restrictions on the size or capability of Russian forces.[5] The security guarantees proposed in the draft 2022 Istanbul Protocol treated Russia as a neutral security “guarantor state” of Ukraine along with the other permanent members of the UN Security Council, failing to identify Russia as a belligerent in the war. The outlined security guarantees would give China and Russia veto power over any action the guarantors could take in response to a renewed Russian attack by granting the UN Security Council the authority to take “measures necessary to restore and maintain international peace and security.”[6] Such “security guarantees” would allow the Kremlin and its allies to dictate the means and tools that Ukraine could use to defend itself against Russia and restrict the ability of other guarantor states to come to Ukraine’s assistance.

The Kremlin is continuing to indicate that Russian President Vladimir Putin is unwilling to have an immediate bilateral meeting with Ukrainian President Volodymyr Zelensky on the timeline proposed by US President Donald Trump. Lavrov stated on August 20 that Putin confirmed his readiness to continue direct negotiations with Ukraine in the Istanbul format.[7] Russian and Ukrainian delegations have engaged in three rounds of bilateral talks in Istanbul since February 2025, which have resulted in nine prisoners of war (POW) exchanges, but little more.[8] Lavrov claimed that Putin would consider raising the level of the delegation heads after working groups had been established but added that a summit between Putin and Zelensky would need thorough preparations that could take time. Several US officials have stated that Putin promised Trump that he would meet with Zelensky following the multilateral summit between the United Stated, Ukraine, and European leaders on August 18.[9] Trump stated on August 18 that Zelensky and Putin need to meet urgently and that waiting too long before having a leader-level bilateral meeting would result in thousands of deaths.[10] Lavrov may have attempted to portray the Kremlin’s proposal of continued negotiations within the Istanbul framework and working groups as fulfilling Putin’s reported promise to Trump to hold a bilateral meeting with Zelensky. Continued negotiations within the Istanbul framework are a far cry from a head of state-level bilateral meeting, however, and Lavrov’s statement is likely part of the Kremlin’s continued efforts to protract peace negotiations and deflect blame for delays onto Ukraine and the West.

Key Takeaways:

  • The Kremlin is demanding that Russia have a veto over any Western security guarantees for Ukraine in an effort to undermine ongoing US, European, and Ukrainian efforts to establish conditions for lasting peace in Ukraine.
  • The Kremlin appears to be demanding that any security guarantees be based on those proposed in the Istanbul 2022 framework, which would grant Russia and its allies the right to veto Western military assistance to Ukraine and leave Ukraine helpless in the face of future Russian threats.
  • The Kremlin is continuing to indicate that Russian President Vladimir Putin is unwilling to have an immediate bilateral meeting with Ukrainian President Volodymyr Zelensky on the timeline proposed by US President Donald Trump.
  • The Russian economy continues to face budget deficits as a result of increased defense spending and detrimental effects of Western sanctions and secondary tariffs.
  • Secondary tariffs are likely forcing Russia to sell oil below market price, which could be decreasing the incoming flow of foreign funds into the Russian economy and depleting Russia’s primary source of wealth.
  • The Kremlin is reportedly considering replacing Russian Investigative Committee (Sledkom) Chairman Alexander Bastrykin, likely as part of the Kremlin’s efforts to form a new and younger elite.
  • Ukrainian forces advanced near Pokrovsk. Russian forces advanced in northern Sumy Oblast and near Lyman, Toretsk, and Velykomykhailivka.

Forced displacement represents one of the most pressing humanitarian issues of our time. Individuals and families, torn from the fabric of their communities, find themselves navigating a world of uncertainty, often without basic necessities or a clear path to safety. There are currently some 110 million forced displaced, and this number is growing by 10 million each year!

At the heart of this crisis are the political triggers. Armed conflicts, ethnic or religious persecutions, and systemic human rights abuses force millions to flee their homes in terror. Many are displaced within their own national boundaries, while others seek asylum abroad. If these factors change as a result of political shifts at home or the pressures from abroad, they can return to their homes. Forced displacement is thus different from environmentally driven displacement, as victims of climate change may never be able to return to their homes.

The ramifications of any sort of displacement are profound, not just for those directly affected, but also for host communities and countries. Overburdened infrastructures, socio-economic strains, and cultural tensions can arise, necessitating comprehensive strategies to foster harmony and integration. Yet the root causes of forced displacement can be remedied with a concerted focus by local players and international diplomacy.

Organizations like Refugees International play a crucial role in this arena, advocating for the rights and needs of the displaced, conducting on-the-ground assessments, and influencing policymakers to take informed actions. Their relentless work underscores the gravity of the situation and the urgency ofinternational cooperation. But they, too, are overwhelmed by the rapid expansion of the crisis.

International Humanitarian Law (IHL), with its core principles centered on the protection of civilians during conflicts, plays a pivotal role in this discourse. Yet, despite clear legal frameworks, compliance remains
inconsistent. This initiative emphasizes the importance of upholding and reinforcing these international standards.

It’s not just about recognizing the problem; it’s about active engagement. We urge governments, organizations, and individuals to prioritize the rights and needs of the forced displaced. Through collective efforts, informed policies, and sustained advocacy, we can shift the narrative from passive acknowledgment to proactive intervention.
