Bring our troops Home?

I keep hearing people yelling, "Bring our troops home" My question is: Bring them home from where? We have troops all over the world and have not left after every military action. Germany Italy England The Netherlands Portugal Korea Japan Guam Iraq Turkey etc... When ever we have a major battle with someone we stay. That is what the US does. Why stop now? Why stop with Iraq? Bring all troops home. How many countries have you been to and were afraid to admit you were American? I have a hard time in Canada. That is only 15 minutes from my house.
