The military doesn’t make policy in this country.
but as a citizen, I reserve the right to agree or disagree with the reasons for fighting...and if I disagree then deciding not to be in the service
if I was at the age to fight (I was much too old) after 9-11, I would have gladly fought. after a few years it just became another debacle as Bush decided to stop putting full effort into destroying Bin Laden and Al Qaeda and finish his daddy's war for him. I grudgingly backed him but was not happy with that.
after pearl harbor Dad joined the USMC and fought the Japanese in the south pacific. That was the good fight.
