Well I wouldn’t call it an invasion as Putin doesn’t want all of Ukraine demographically.....even the break away republics are only recognized. But Putins been staunchly clear for decades Ukraine was his red line.....and Nato/US just plain went to far in all the military equipment and armament they’ve been flooding into Ukraine for years now....and he’s targeting all of that.
The way you describe it would make it seem we are the aggressors (and you might be right - I don’t trust any honest or impartial reporting here in the US).
They’ll sort it out.
NATO was designed to stop Germany from tearing through Europe every quarter century; I don’t even see the point of its expansion. It just feeds the primitive fear of “encirclement” from WWI days...
