An interesting read and I agree with the first quote that Russia will continue to pursue its political objectives (subjugation of Ukraine) as long as it as the military means to do so.

The policy question for the US remains what we can and should do about it. Obviously, that is a bit contentious. My personal opinion is that I’m more than willing to give away older munitions and fight to the last Ukrainian. The Russians aren’t our friends and anything that weakens them is fine with me. It’s a very “Real Politik” position, but that is the kind of world we currently inhabit.
