Why does Europe and America have such an extensive history of sticking their nose into other country's busines?

It's none of our business what happens in the middle east as long as they don't bring it here. We were in the middle east before 9/11 so don't say - "they did - 9/11." No imperialistic country has ever survived long because you can't just go into countries and force the people to change their cultures. The people will rise against you and you will fail. What works for us does not work for them. China with all it's military force isn't using it to try and control the world. Our troops need to be home and America needs to start minding it's own business before nations rise against us and we'll be living like we're in a 3rd world country.
