No matter what happens anywhere in the world, the Dinocon dogma is the same "Hide out in Fortress America and do nothing".
It amazing how in a post 09-11 world the Dincons still cannot wake up to the plain fact that there is no place for them to hide anymore.
These foes will come to you if you do not go get them 1st. These foes have no desire to "live and let live".
Modern economic-political reality? You mean because the world is so much more dangerous now than when isolationism was considered a mainstream policy?
Even though it isn't true. The world was incalculably more dangerous 250 years ago when isolationism was preached far and wide.
Presidents were preaching isolationism when Indians were scalping men, women and children on the frontiers. They were preaching isolationism when the Ottoman Empire was a great world power. They were preaching isolationism when a cholera epidemic could wipe out an entire town's population in weeks and 1 in 10 women died in childbirth.
They were preaching isolationism because even with all those dangers, they knew a government ever expanding its martial circle was the bigger danger.
