“Because the U.S., Europe and Ukraine want the war to end.”
What planet are you living on? When Boris Johnson went to visit Zelensky last week, it was reported that Zelensky proposed negotiations with Russia to end this war. BoJo told him no, that neither the UK or the US would allow it.
You are going to claim it, you get to back it up. Sources, please? Other than taking your own hyperbole seriously into what others have reported.
By the way, Johnson visit Ukraine on April 10, not last week. That was after talks in March between Ukraine and Russia broke down. Johnson encouraged Zelensky to keep fighting because negotiating with Putin was pointless. The U.S. and U.K. did not tell Zelensky not to negotiate and did not stop Ukraine from trying to reach a settlement.
