Somewhat inspired by a post by Victor where he stated that he would like it if America withdrew their military from Australia.
I started wondering, what would be the effects if America did this to the extreme? How would the world be affected if America suddenly withdrew all of its forces from everywhere they are deployed and brought them back home?
On top of that, having isolationist policies would imply that we would no longer attempt to influence foreign policy, help countries that need help, enter economic agreements, etc.
What good or bad could come of this? I often hear people complaining about America's involvement in things, so what would happen if they got their wish, and we stopped?
(I was thinking of putting this in politics, but it said "past and present" and this is a theoretical future, so I put it here...)
