What is the reaction in Ukraine to U.S.-Russia talks happening without Ukrainian representation?

The feeling in Ukraine is one of extreme anxiety. President Zelensky postponed his visit to Saudi Arabia specifically to avoid bestowing any credibility on talks happening without him, demonstrating Ukraine's concern about being sidelined in negotiations affecting their future. Both Ukrainians and Europeans find themselves in a weak position, as the Europeans lack the military might to push back against Russia without substantial U.S. support. Europe has always relied on Washington's massive military funding, making alignment with the United States crucial for any effective resistance against Russian aggression.
