Explanation: The US during the Cold War leaned into Christianity as a means of differentiating ourselves from the 'godless commies'. The Soviet Union supported state atheism as a means of stamping out superstition. After the Cold War ended, the trends reversed, with atheism surging in the US, and Christianity seeing a revival in Russia.
Maybe Trump is going to speed up the population's atheism arc. Restrictive religion-inspired laws can have that effect - see Spain after Franco. Though Trump himself doesn't do a good job at even pretending that he cares about religion.
I don't believe the cold war ever really ended, russia just got new managment and we all calmed down a bit. we are still doing the whole nuclear dick measuring thing and we are almost certainly still doing a good bit of spying. we still base a lot of decisions on the possibility of inciting nuclear war. we even have more countries doing it now. so, it never ended.
