re: #48 Targetpractice
And after that a way for defense contractors to make huge wads of dough digging massive underground silos, building the missiles to go in them, putting missile-carrying subs to sea, building and maintaining intercontinental range bombers, and the occasional foray into experimental ways of reducing patches of land/sea/sky into radioactive byproducts.
Still far cheaper than trying to fight a 40-year cold war with a 100-division army and 2000-ship navy. We would have been locked in a Sparta-level economy and social structure. Learn to love the Bomb.
