If we don't soon extricate ourselves from supporting those other countries with military presence on their soil (which in many instances causes resentment of the US by the general population of those nations) those treaties will become a moot point as we'll be unable to continue there once our economy and then society collapse under the burden of continuing those foreign programs while simultaniously taking care of our domestic issues. If we continue down the path we're on, we won't be able to do anyone any good. I don't believe the US set out to become an empire, and I don't think of it as a true empire, but we've become an unintentional empire and empires always become spread too thin and then fail. We're not in the cold war anymore and it's time to concentrate on taking care of things at home instead of defending the rest of the world against an enemy that isn't there any more. We can maintain a strong military without intruding on other sovereign nations and perhaps improve our relations with those nations in the bargain.
