I understand that having an involvement with much of the rest of the world can be important, I think that we could bring back a number of our military forces and still have a strong ability to help other people in the world. It can be a tough issue though and I can understand why some people would want to have them there.
At some point in time America became the policemen of the world. Because of that we are always putting our people in harms way in order to watch out for countries around the world. Because of the world relying on us to be strong and supportive we need to have a military that can stand up to all of this pressure. We should always have money in our military to protect our interests.
