My money is on Putin bluffing to attack. The last thing he wants is a long protracted guerilla war within Ukraine against rebels armed with Western weaponry.
He definitely wants his buffer zones between Russia and NATO codified though.
Also, Russia is as dependent on Europe as a buyer of natural gas, as Europe is dependent on Russia for said gas. All this screams irrational insanity.
Then again, is Putin sane?
Extremely transparent. He tried to do the same to Obama with Crimea.Hes been inching towards it for years. Timing might be partially as a play to apply pressure to Biden and possibly make him look weak
