Is USA the global police? or a Potential Reason for third world war?

As I get older I can see the harm that our government has and is causing, but that doesn't mean that all Americans agree with what is happening. Love it or hate it, we are a world power. Someday, I pray, that power will be used wisely.

Might I also add, that were it not for the US, there are a lot of countries that are free and loving it now that never would have been without our help. Do you think Hitler would have been stopped? AND, if not for lots of American companies in India, the lifestyle many of India's youth are beginning to enjoy would not exist. I would say the US is an ally in more ways than just in wartime, we are for global, peaceful commerce.

Okay, first of all the US has a military trained to fight any war, why would we fight a war on our land when it isn't necessary. It's the goal of any military to prevent wars on their own soil. The US isn't trying to police the world, we're trying to protect ourselves. For some reason every other country in the world tells all it's people that the US sucks or that we're all dangerous and mean people. But they all want our assistance during their own tragedies and turn their backs when we need their help. I am frankly tired of all these people from other countries telling us that we're bad people. Can you not stand that we have freedom, that we have free will, that we protect ourselves and will always protect ourselves. It's called being proactive. Pearl Harbor started here and it didn't continue here because we don't want our people killed, and there aren't many countries that have the gumption to attack us. We will at all costs protect ourselves as we have shown the world. And we are willing to protect countries that stand with us and are for a fair and democratic process when dealings are necessary. I wouldn't say the UK is blindly following anyone. They're smart people and they also see that the threat of terrorism is real and needs to be handled not just for the US and UK's protection, but the whole world. Terrorism is fueled by hate that has no rhyme or reason. That should scare EVERYONE.
