We can deploy anywhere around the world from america in a few hours. We have orbital weapons and other tech to handle the rest. Having troops on the ground in the me is a long dead idea. We are going bankrupt, things need cutting. SA, China and the rest can stand up now.
My thoughts, too. The next war, and unfortunately there could very well be, will be fought by pushing buttons with missiles flying back and forth. Ground troops are rapidly becoming a thing of the past.
Only if you have a country willing to let you use their air bases. We already have that in Afghanistan. I would be foolish to give it up.
