Why Putin Chose to Invade Ukraine Now? Was NATO Expansion to Blame? A Chat with William Wohlforth

Russia has met unexpected stiff resistance from the Ukrainian army since day one of their invasion.

But can the Ukrainian army really drive out the Russians without NATO imposing a no-fly zone and sending ground troops?

How well will sanctions work?

And is Putin adjusting his goals in Ukraine already?

And who really bears the responsibility of starting this war?

I had these discussions with William Wohlforth, Professor of Government at Dartmouth University.
