That's what I said. Fuck Putin. It should be Ukraine's call. But if he keeps Crimea he WILL come for more. That will guarantee thousands more lives lost. Or millions...
A few things I think are certain with putin. 1. He wont give up Crimea or any part he has gained. 2. He will continue his war on attrition to try and take all of Ukraine 3. He will no doubt Nuke Kyiv if he thinks it's necessary. The only way he's eliminated is, if his people are starving and he's taken out either from one of his generals or one of the oligarchs. Hardcore sanctions are needed. Or, troops are sent in as a peace keeping force by calling his bluff.
If he's going to keep trying to take Ukraine anyway then there is no reason to give up Crimea. I don't believe he'll nuke Kyiv. Closest he'll come to it will be hitting a nuclear power plant, IMO. If he were to use nuclear weapons the world would demand his removal. That's the end for him. *Edit* Even blatantly hitting a nuclear power plant may be enough...
