In a significant diplomatic engagement on December 11, 2025, Ukrainian President Volodymyr Zelenskyy, along with his advisory team, conducted a video conference with key U.S. officials to discuss the security guarantees critical to Ukraine’s safety and sovereignty. The conversation, aimed at fortifying Ukraine’s defenses against potential aggressions, particularly from Russia, included high-profile U.S. participants such as Secretary of State Marco Rubio and Secretary of War Pete Hegseth.

During the meeting, which also saw the involvement of NATO Secretary General Mark Rutte, President Zelenskyy underscored the importance of the U.S.’s involvement at various levels in helping end the ongoing conflict and securing Ukraine against future threats. The dialogue centered on one of three essential documents designed to pave the way for peace and prevent further Russian incursions.

Highlighting past breaches by Russia, including the infamous Budapest Memorandum violations, Zelenskyy stressed the need for explicit security commitments from international partners. The discussion focused on detailing specific actions that would be undertaken should Russia exhibit renewed aggressive intentions towards Ukraine.

The outcome of the meeting was a mutual commitment between the Ukrainian and U.S. teams to clarify and solidify the terms of the security guarantees. Both parties agreed to continue their collaborative efforts to ensure a robust and unequivocal understanding of the security measures that would be mobilized in defense of Ukraine’s integrity.
