Trump would be civil war AND WWIII. The dude already said he's for the genocide of Gaza and everyone knows he loves Russia and China. He would also end Democracy within the US.

For a Trump presidency, do you mean a civil war happening during WWIII? Because that man wouldn't do jack shit about stopping that from happening. He'd just join his buddy Putin's side of that conflict, supposing the civil war resolved in his favor. And supposing WWIII's nuclear Armageddon ending isn't reached before that point.

Biden's foreign policy is an aggressively boring continuation of what US policy has always been. Lol no.

whereas Biden remaining in office drastically favors WWIII.

LOL, nah. Biden vs. Trump is basically a wash in that respect.
