In a significant phone call with US President Donald Trump on Saturday, Ukrainian President Volodymyr Zelensky clearly outlined his doctrine for achieving peace with Russia, a strategy centered on the principle of strength. The conversation used the recent Gaza peace deal as a backdrop for a broader discussion on the necessary preconditions for ending the war in Ukraine.
Zelensky’s doctrine was articulated in a simple but powerful statement: “There needs to be readiness on the Russian side to engage in real diplomacy—this can be achieved through strength.” This philosophy shaped the entire “productive” call, framing every request and observation within this strategic framework.
The call began with praise for Trump’s diplomatic success in Gaza, which Zelensky used to argue that peace is possible. However, he quickly pivoted to the specific conditions required in his region. He briefed Trump on Russia’s attacks on Ukraine’s energy grid, presenting this as evidence that Russia currently only respects force, reinforcing the need for his “strength” doctrine.
This led directly to a conversation about military reinforcement. Zelensky and Trump discussed “concrete agreements” to bolster Ukraine’s air defenses. From Kyiv’s perspective, these are not just tools of war, but instruments of peace—the very “strength” required to bring Russia to the negotiating table in good faith.
By laying out this doctrine so clearly to his most important ally, Zelensky is seeking to ensure long-term, robust support. He is making the case that military aid is not an obstacle to peace but the only viable path toward it. The call was a crucial moment in aligning the US and Ukraine on this fundamental strategic principle.
