The US is regularly engaged in diplomacy with Russia. Our secretary of defense and chairman of the joint chiefs just met with their Russian counterparts.
Diplomacy is happening. That doesn't mean peace can be negotiated yet. Unless the commenter thinks Ukraine should surrender, it is unlikely peace is going to be realistic anytime soon.
Ok, I re-read it. It was just as violently stupid the second time around.
"Diplomacy" doesn't mean "I break into your house and agree to take only 10% of your stuff if you don't fight back." And when the cops show up, that's not a "proxy war."
