Now I feel I was wrong and Trump is just averagely warmongering, as US presidents go.
It was also consistent with a broader policy of isolationism shown during his first term. Reducing support for NATO, backing out of trade deals - all consistent with America First and not being the world's policeman, which has been the US's justification for every war in the last 80 years.
I'm not American, so probably have a different perspective on this from Americans. But also that's a reason for me to judge a US president disproportionately more on his foreign policy than on say, healthcare or which bathroom people should use.
Joe Biden. Unless you'd contend that withdrawing from Afghanistan was an elaborate, self-owning plot to overthrow the US-friendly government in favor of the Taliban, which I think goes against the spirit of your question.

> Administration officials deny that they aided Hayat Tahrir al-Sham (HTS), the U.S.-designated terrorist organization that led the drive to overthrow Assad, but they insist that they facilitated the opposition’s victory, citing years of U.S. efforts to empower the opposition and weaken the Syrian government.
> U.S. policy “has led to the situation we’re in today,” State Department Spokesperson Matthew Miller said in a December 9 press briefing, the day after Assad fled the country. It “was developed during the latter stages of the Obama administration” and “has largely carried through to this day.”
An Obama-era policy, kept in place through Trump's first term and then through Biden's, ultimately resulting in local forces overthrowing a dictator that nobody liked, does not count as Biden being a warmongering regime changer. Your source even goes on to say that Biden was so dovish on Syria that senators were beginning to suspect he wanted to find a deal to keep Assad in power. What evidence do you have for funding local terrorists in Syria?
