This is interesting but I also think it misses the forest for the trees a little bit as the second half of the 20th century paved the way for many of the problems we currently face. The deep state became entrenched, the CIA started demanding endless wars, the Soviet Union was finalizing their infiltration into Western society etc. GK Chesteron's quote about conservatives failing to conserve anything comes to mind and he's been proven correct again and again.

Conservatism doesn't seem to do very much except provide the most basic of templates for approaching life which is all fine and good except that other ideologies also provide similar templates. Conservatism after all set off the Gulf War.
