There were a lot fewer extreme events between 1935 and the 90s. It is getting back to normal now. This is what the world normally looks like.
A few big wars and hundreds of millions killed by Communism and souls poisoned by secular progressivism...millions of babies killed by abortion. Accelerations of the murders of christians in islamic lands. A couple of nuclear city busters dropped on Japan. A general loss of moral coherency and great apostacies in both Catholic and Protestant churches. Currency manipulations and the bankruptsy of nations.
Not a lot of extreme things happening between 1935 and 1990!
