I have become of the mindset we need to bring all of our troops home- close all foreign bases and bring our sons and daughters home. Let the other countries take care of their own defense. Besides, after what obama and Burden have done to our country we need all the troops here we can get to defend ourselves from the jihadis, etc.
I think that the original idea was to fight wars on their soil, and leave the US cities unscathed.
I suspect that the next war will not notice whether or not our children are on our own soil, or some other tyrants soil.
