Who will play the crucial role in providing security guarantees to Ukraine amid tensions with Russia?

According to Marc Polymeropoulos, the European powers will play the decisive role in providing security guarantees to Ukraine. He notes that President Zelensky feels betrayed, and while US leadership remains important, the responsibility will ultimately rest with European nations to ensure Ukraine can continue its struggle against Russia. Polymeropoulos references a meeting in Paris and suggests that European coordination is essential for Ukraine's ongoing defense. This indicates a shift in security dynamics where European nations must take greater ownership of supporting Ukraine, particularly as questions arise about the consistency of US involvement in the conflict.
