He wasn't at the beginning of his last term

Defeated ISIS in Iraq/Syria, increased forces in Afghanistan (and stopped the planned drawdown) before decreasing at end of term, established maximum pressure campaign on Iran, raised (then lowered) potential conflict with NK.

However, I do believe things have deteriorated to the point where he, or any Republican nominee, might be much more "America First" this time. We just aren't in as strong of a position as we were at the beginning of his first term (a decline accelerated by COVID and spanning two administrations). Our financial, civil, and military strength are all worse off and in need of focused attention.
