Removing foreign mobile military units? Sheesh.
I can understand "some" reasoning for the other two...but really? Cutting us off at the knees?
Although I was not in the military, I can offer some advisement on it because I lived it as a child of a career Navy veteran. I lived on foreign bases - at one point being at ground zero for submarine naval operations in Europe during the first Iraq war. Foreign presence has significant value, even in today's world.
Don't believe me? Look at Russia...they've recently started opening foreign presence again.
While taking care of "us" here is important. It starts on their territory. Not ours. Border security quality aside (not a manpower issue), our capabilities here are vast. Sure, nothing is foolproof, but when we need to rain down some power, we can and will - a drive to Fort Campbell or NAS Oceana or Norfolk is great evidence.
As a kid in more "lenient" times in the military, I was afforded access to things that many people never got to see. I know what it feels like to touch and handle a weapon that can wipe out an entire city and millions of lives. Just being around it made me nervous - yet we harness it with extreme precision. Imagine many of these sitting on a submarine with a broken propulsion component in the northern atlantic...how does it now get fixed if we have no foreign presence?
