I still think the way to go is to put pressure on the billionaire oligarchs. Essentially blackmail them into being our asserts. Give them the horrible choice or having everything seized and losing it all unless they can find a way to lead the charge inside Moscow to overthrow Putin and stop the war. If successful, they can keep all the money, yachts and luxury apartments in Miami and NYC. If they fail, they will probably be executed by Putin and we seize all their assets anyway
