Putin is crossing the border, count on it. He knows the weakness of Biden and the west will only put up a token resistance, wring their hands and whinge. Two reasons Putin will invade the first is what everyone is yammering about but is essentially irrelevant is that he wants to restore the former USSR as much as possible. Yeah, sorta but BS. Putin is interested in world power. POWER! With that the reaquisition of buffer nations will follow. So why does Putin want Ukraine? Because they have something Russia lost with the dissolution of the USSR. HUGE shipyards capable of building and maintaining capital ships such as aircraft carriers. Period. Ukraine has three major shipyards with that capacity and Russia currrently has one. Russia has one crappy aircraft carrier that’s constantly breaking down and they have no shipyards to maintain it. Putin had to buy from Germany a huge, mobile floating shipyard to repair the Admiral Kuznetsov and it SANK while the Kuznetsov was onboard undergoing repair! No, Putin very much wants those huge shipyards so he can start building aircraft carriers and maintain them.
