What concerns are European leaders expressing about their role in Ukraine negotiations?

European leaders are expressing significant frustration over their limited involvement in Ukraine-Russia negotiations. They argue that after spending billions to support Ukraine, they deserve more than just a seat at the table when it comes to economic negotiations and sanctions removal. Their concerns stem from the fact that long-term responsibility for safeguarding Ukraine will likely fall heavily on Europe. These leaders are pushing for more intimate involvement in the diplomatic process, particularly since they will bear substantial responsibility for Ukraine's future security and support. The frustration, while notable, is not surprising given the shifting approach to the conflict and the potential implications for European security interests.
