Just yesterday the U.S. reiterated its stance it is not seeking to promote a negotiated truce between Ukraine and Russia that could end their month long war. It also re-stated that the best help in can provide is to flood more weaponry into the war zone.
That is even dumber than the dumb US policy since 2008 of dangling NATO membership to Ukraine, supporting a coup to topple the Russian leaning elected Ukraine president, then arming and training the new ultra nationalist government to fight the civil war ignited by that US coup. Over 13,000 have been killed in the Donbass, mostly Russian speaking Ukrainians, in the 8 years since.
