now the story changes: the war that putin started in 2014 is not the fault of Biden, but the fault of the foreign policy of everyone except the former guy?

instead of the dude who actually started it with the invading?

you also seem to misunderstand that Putin has been "touching Ukraine" since the war started in 2014, and the former guy did nothing to stop the war

I'm not saying Putin isn't responsible. That's as obvious as crickets. If people didn't commit evil, the world would be perfect.

Obviously, people commit evil.

However, if you are charged with authority, it is your responsibility to defend against evil, while also pushing to being about peace. Obama and Biden did not keep evil in check. Trump did so much more, as ironic as that may seem to you.

the former guy did literally nothing to push back against the evil of russia's invasion and genocide of Ukrainians which started in 2014 and lasted his entire term (aside from trying to extort the victim for personal political favors and getting impeached for it), as ironic as that may seem to you

You are correct in your statement "If I was Putin, and I wanted to invade a country". Putin wanted to invade. Its his war, nobody else's.
