Call for regime change? Biden departs from script to blast 'butcher' Putin

Is this just a bit of hyperbole that will soon be forgotten as the world watches Russia bomb civilians and push its invasion of Ukraine? Or a moment as significant as when Putin issued a thinly-veiled threat of nuclear war last month to deter the West from intervening? We dust off the Cold War playbook to see what works and what does not. 

More broadly, with Biden back in Washington and both sides digging in for a long war, we ask if anything can stop the nightmare that is unfolding and also how Russians themselves feel about it all.
