Did you ever end up serving after?
Military members go to war because of politicians and fight and die for each other, that sacrifice can never be down-played.
While a military member is on operations, they have to believe in the mission.
Nobody wants war.......but there are times when intervention against oppression is necessary, evil lurks out there and someone needs to step up to fight it even if it is a losing battle....Vietnam was a lost war due to political interference, the US shut it down before it escalated into a larger war involving many other countries one of which was China.
Patriots of all classes volunteered to fight...WW2 saw many actors and famous people in uniform fighting for their country. Korea, Vietnam, even Iraq and Afghanistan had famous people in uniform because their country came before themselves.
