I’m not sure about the Biden cooperating with Al Qaeda thing (perhaps you mean not intervening when HTS took over? Biden was backing the Kurds at the time) but it was Trump who did a deal with the Taliban re Afghanistan.

The post war Republican Party had been all about building alliances and being nice to allies! The current Republican Party is so different and distant from the stances of the party just 20 years ago.

Cooperating with Al-Qaeda is a decades-old policy—started under Clinton, brief pause after 9/11, then returned in full force in late Bush years (2007 "redirection") and hasn't stopped since.
