That makes no sense. So basically, he remained chill with Trump in office AND tried to cheat to get him in office a second time (that's what the left says) knowing full well he would not be able to invade another country for another four years? And if he's corrupt enough to get puppets in the US White House, he'd probably have more he'd cheat to get in office, probably enough to last until his death (and if not he could pull a Stalin and pay people in the US to monitor and influence the president). But then his "cheating" failed, Biden's in office, so he goes, "oh what the heck, might as well take back the country that escaped from the USSR in 1989, the one I've always wanted back. It's okay now, none of my puppets are in the US office."
That makes absolutely zero sense. Either he wants one thing or the other, because if both of those things are true, he cannot possibly get what he wants out of any situation.
Also, Biden has pretty much had conversations with Putin where he just gave him everything he wanted. I'm telling you, Putin is much happier now than he was 2-5 years ago.
