In my lifetime, we have not been through a declared war, but have had our troops killed in Korea, Vietnam, Cambodia, Lebanon, Sudan, Croatia, Panama, Kuwait, Iraq and Afghanastan. No doubt I missed some, probably Libya and Iran. Some have been under the command of the United Nations. It seems like we are always somewhere. Threads could be done on each of these places as to whether the sacrifice was necessary. Where do you think the next conflict will be that we get dragged into and why?
