Analysis shows challenges in offering Article 5-like security guarantees for Ukraine, indicating legal and practical hurdles.
The question of possible security guarantees is at the heart of current efforts to end the war against Ukraine. White House special envoy Steve Witkoff stated on 17 August 2025 that “the United States and other European nations could effectively offer Article 5-like language to cover a security guarantee,” which would serve as a trade-off for Russia’s insistence that Ukraine should not be able to join NATO. This has brought the term “Article 5-like protection” into focus. The feasibility of such a guarantee appears impossible given legal and practical obstacles. Russia is demanding untenable concessions from Ukraine in exchange for its consent. The prospect of a credible deterrent is also missing, which is why the entire process appears to be the Russians playing for time.
