Polish Foreign Minister Radosław Sikorski questioned the effectiveness of talks of security guarantees for Ukraine, suggesting the term itself may be misleading, according to European Pravda.

In recent months, Ukraine’s western partners have been discussing “security guarantees” aimed at preventing further Russian aggression in the event of a ceasefire. 

Proposed measures include formal security treaties, peacekeeping forces, military support, and economic sanctions. However, the effectiveness of these guarantees remains unproven, as they largely depend on Russia agreeing to a ceasefire in the first place.

Speaking at the annual Yalta European Strategy meeting in Kyiv, Sikorski said that Ukraine already had “guarantees”, even if they were called differently, in the 1994 Budapest Memorandum. 

The Budapest Memorandum was an agreement signed by Ukraine, Russia, the United States, and the United Kingdom that was intended to safeguard Ukraine’s territorial integrity and sovereignty in exchange for Kyiv giving up its nuclear arsenal.

Sikorski argued that any new, more concrete guarantees would likely fail to deter Russian aggression.

“The purpose of security guarantees is to deter Russia from renewed aggression. In essence, if we give security guarantees to Ukraine, we are saying we could go to war against Russia,” Sikorski said. 

“I don’t think that’s convincing. Who wants to fight Russia? I don’t see many volunteers. In international relations, nothing is worse than offering guarantees that are not trusted.”

Sikorski called for a shift in focus away from guarantees, urging instead for monitoring of peace and strengthening Ukraine’s capabilities. 

He also emphasized prioritizing military and financial support, warning that prolonged discussions on guarantees could distract policymakers from urgent funding needs for 2026 and 2027.
