The thing is, we could halve our military spending.. and still be spending more than any other nation in the world on our military. Reducing our military spending will not allow china or russia to suddenly go and conquer the united states. Russia is a skeleton, with an obselete navy and nuclear arsenal, small military, and no force projection whatsoever. China hardly fares better. Despite what military-industrial complex scare tactics would lead you to believe, we are not at risk of falling behind the rest of the world in military strength or technology, and we won't be even if we cut our spending on a huge scale.
