Although the Congress authorized military action during those periods, they never passed a formal declaration of war, so these conflicts are referred to under the law as *Periods of National Emergency*. But if you served during the authorized period, you are considered to be a veteran of that war, regardless of where you served.
James, your new information is most interesting to me. However, knowing a few who served in country during the Viet Nam War, one of whom did not return and two of whom came back completely different people, then speaking only for myself, I think it all boils down to the distinction between Congressional reality and real world reality as to whether I claim "to be a veteran of that war."
In all good conscience, I cannot make that claim regardless of what Congress authorizes - my big problem lies with the "regardless of where you served." part.
Thanks for your clarification.
