The undeniable fact though is Americas foreign policy has always and probably will always be a shambles, because it is based on bringing 'freedom and democracy' to other countries, however only if that freedom and democracy lines up with America, otherwise it's not regarded as valid, hence overthrowing legitimate governments on numerous occasions, supplying arms to whoever is the current flavour of the month with them, and years later having to blow up those same arms when they regard their friend as a new enemy.
It's a dying empire, and like all dying empires it's a dangerous one, biggest threat to world peace isn't the Russians, or Chinese or even terrorism, it's an empire trying to hold onto what it once had, history shows that and America is following the same markers all falling empires do.
