CNN today reported that in the last few days (and since the riots) the Trump administration has opted, as part of its final act, to hand Biden a whole new set of international diplomatic dilemmas; they have just:
Named Cuba a state sponsor of terrorism;
Designate Yemen's Houthi rebels as a foreign terrorist organisation;
Upended decades of US-China diplomacy by lifting restrictions on contacts between American officials and representatives from the self-governing island of Taiwan.
Trump just being Trump. No surprise there. What a bitter man.
