Nonsense. The Swiss were totally surrounded by the Nazis but they never attacked. A defensive army is possible. The only reason the US gets hit with terrorist attacks is because jerks like you insist on playing war games all over the planet.
You still haven't answered the question. I don't want your "protection". Why do you force me to pay for it?
Who's forcing you? If you're an American citizen, renounce your citizenship and sign on as a Costa Rican citizen. And how do you figure we're instigating terrorist attacks against the U.S.? And why do I waste my time with a traitorous idiot?
