Biden didn't.You say that as though Biden had nothing to do with the issues in Israel and Ukraine.
Putin was building up forces all along the border with Ukraine for four years, including in Belarus. Putin was banking on Trump being re-elected. When Trump lost Putin had two choices, Attack, or withdraw. Putin chose to attack. That is what occurred. Agree or not, it doesn't really matter, since Russia did invade.While Trump was in office, Russia didn't dare attack Ukraine because they knew he would fire back and it would be not good. It's funny that Russia was not willing to do what they're willing to do now under Biden, but you want to say Trump is Russia's puppet... When Russia clearly was quite scared of Trump.
Now what is your stance on the invasion? Regardless of Biden or Trump, Russia signed an agreement to protect Ukraine, in exchange for Ukraine turning over it's nuclear weapons. The US also agreed to protect Ukraine,and signed the same agreement. So far Ukraine has been fucked by both countries.
Netanyahu got re-elected, and as he has voiced in the past, he is acting on killing off Hamas, be damned who gets in the way. Nothing Biden, or Trump said or did would have prevented this. Hamas attacked and that gave Bebe all he needed...As far as Israel goes,
