While I would agree that Ukraine should give up Crimea, I would not agree to any other territory. I think Putin would actually go for that if Ukraine offered that and to remain neutral. Anything else though is a non starter. Russia is in deep trouble economically now. Indexes used to rate countries livability and standards are not painting a good picture for Russia. 50% of the government revenue is from oil and gas, and no matter how much China can buy, they cant make up for the entire EU. Revenues down, vital war machine resources almost completely depleted, and western goods are gone. By September at the latest, things will be pretty bad. By winter, things will be dire for Russia and Ukraine.
Meanwhile more MLRS got to Ukraine this weekend, and 4 more from US and 4 from England are on the way. Giving Ukraine 16 and a whole lot of missiles to fire from them. A gas station inside Russia just blew up too. Funny how many things are blowing up and catching on fire in Russia these days.
Poland though has more US military spending $$$ on weekend passes all over the country. Not bad for the economy at all.
