How are European leaders and Ukraine responding to the U.S.-Russia talks in Saudi Arabia?

There is a great deal of frustration being expressed regarding the development of U.S.-Russia talks in Saudi Arabia, particularly from European leaders and Ukrainian President Zelensky who feel sidelined in these negotiations. The talks represent a significant diplomatic shift where the U.S. is pursuing direct negotiations with Putin to end the Ukraine war. This approach aligns with President Trump's longstanding views toward Russia, as he has always demonstrated more affinity toward Putin compared to his predecessor, President Biden. The U.S. strategy of bypassing Ukraine in these peace discussions has created tension with allies who believe Ukraine should have central involvement in determining its own future.
