Russia started its invasion of Ukraine in 2014, not 2022.

"On 24 February 2022, Russia invaded Ukraine"

https://en.wikipedia.org/wiki/Russian_invasion_of_Ukraine

From your source:

"in a major escalation of the Russo-Ukrainian War, which started in 2014."

Russo-Ukrainian War: "The ongoing Russo-Ukrainian War began in February 2014. Following Ukraine's Revolution of Dignity, Russia occupied and annexed Crimea"

Biden started those wars? American troops are on the ground in those conflicts?

Naughty old Biden used his time machine to force poor innocent Putin to invade Crimea in 2014, clearly.

Trump would (has promised to do so on live television) just give Ukraine to Russia. Biden/USA/allies have stood down Russia, which has been seriously damaged both by battlefield losses, by not achieving their strategic goals and instead entering a second Afghanistan, and by the rapid conversion of the EU economy to no longer need Russian energy.

I think you are spot on (and a bit puzzled why you got downvoted). The energy transition in Germany away from Russian gas was a economic achievement I didn't think possible. It costs Europe dearly but has accelerated renewable transition remarkedly.

What would trump have done other than not helping Ukraine at all and allowing israel to kill even more civilians?
