Poll: how many people believe that the U.S. should stay out of foreign wars?

That, the United States should keep our military strong and to protect only direct and indirect threats to our homeland. I realize that some other countries cannot defend themselves, but this is a situation that has existed for many years. Defending foreign countries one major reason the U.S. economy is in the shape it is today. Question: would the $100 million dollars spent on Iraq have helped our economy? If not, at least it would have kept our troops from being killed in a questionable war abroad. Lets keep our money and troops at home. Agree?
