Seems most veterans don't agree that any recent war has been worth what has been sacrificed.

Veterans doubt value of wars in Iraq, Afghanistan in new poll
Most veterans believe the wars in Iraq and Afghanistan were not worth fighting, and a majority also view U.S. military efforts in Syria as too costly in dollars and casualties, according to a new poll from the Pew Research Center released Wednesday.
In a survey of nearly 1,300 veterans conducted in May and June, 64 percent of those surveyed said the war in Iraq was not worth fighting, as opposed to just 33 percent who said the security benefits outweighed the sacrifices.
For Afghanistan, 58 percent of veterans said that fight was not worthwhile, versus 38 percent who believed it was. Results from both questions closely track with the opinions of the American public at large.
More veterans also had a negative view of U.S. involvement in Syria (55 percent) than a positive view (42 percent). Pew Research officials said the rate of support for each of the conflicts did not change significantly for veterans’ different eras of service, military rank or combat exposure.
