a deal can be made with Russia to end the fighting [in Ukraine].
How do you know? My impression is that any deal without security guarantees from the West will just be violated in about two years or so by Russia, and Russia would refuse to make a deal with such security guarantees for exactly that reason.
If Russia changes its mind and says it would be willing to accept such a deal, I would change my mind. Actually I still wouldn't because Russia are the lyingest bastards I know, but whatever. It hasn't happened. It would never happen.
Imperialists cannot be reasoned with without credible threats of violence. If it were otherwise, they wouldn't be imperialist.
I'm almost afraid to ask, but what is the 22?
