Biden literally started a war
The American plot to drive Ukraine away from Russia goes back at least 10 years. Our plot to stoke fascism there goes back probably 70. Biden was in office when the war popped off, but using Ukraine to antagonize Russia is one of the clearest examples of a bipartisan foreign policy consensus. Had Trump won in 2020 we'd be about where we are now on the war.
Contrast this with Trump much more literally committing an act of war against Iran by assassinating Qasem Soleimani. This is after he tore up the U.S.-Iran nuclear deal for no reason.
