You're like Ron Paul....clueless about national defense.
FYI...you're talking to someone in national defense and my clearance is far above Ron Paul's clearance if he's even allowed near anything.
No, he said that we should pull the troops back to defend our borders here....which is a legal tightrope having military enforce civilian law enforcement rules.
So leaving Germany, Japan, etc to guard our border against Mexicans and terrorists. Yeah, we'll post the troops on every square inch of the US border to make sure nobody sneaks by us.
We have this group called the US Border Patrol, increase their numbers and give them more technology....the military has nothing to do with "guarding the border" unless you're talking about a military attack from say Russia, China or Iran...but I prefer to fight them over there than here.
Civilian law enforcement rules? No our troops are to protect america, hence guarding the places we're most vulnerable i.e. our ports and borders.
We're not vulnerable in Bolivia or Germany, and we don't need to launch cruise missiles at Libya and Afghanistan in order to keep them from taking over the U.S. So again, that's not for defense as our border security is.
