Wouldn’t be any attacks at all, if USA stayed in it’s own borders and had respected the borders of Ukraine, hadn't arranged any coups in Ukraine, or supported neo-nazi nationalist groups there and didn't push it into NATO
Have you not read Putin's address of February 21? He makes it clear that he considers Ukraine as rightly part of Russia. He attacked, not because of western provocation, but because he thought he could get away with it.
BTW, Russia's definition of a "Nazi" is any Ukrainian who promotes a national identity separate from that of Russia.
