The argument that Ukraine should negotiate for peace with Russia, is 100% Russian propaganda.
Russia started this already back in 2014, they invaded 3 times completely unprovoked, first Crimea, then Donbas, and finally attempted to take it all. The on reasonable form of peace, is that Russia withdraw completely out of Ukraine including Crimea.
And sanctions against Russia must continue, until they have a regime change that is more trustworthy.
