As much I detest both Johnson and Trump, it's Duterte and Bolsonaro who really fucking scare me. I definitely feel horrible for the citizens of the Philippines and Brazil... well at least the innocent ones who didn't vote for the tyrants.
Those other two don't have nukes, like Johnson and tRump. I don't know the U.K. 's chain of nuclear use however.
This Cheeto thing is actually a world-wide phenomenon, sadly/scarily.
