What son? Since my entire future was already in the hands of the US military and therefore having no control over anything I registered for the draft on my 18th birthday and entered a holding pattern until I heard from it.did you want your son to stay there and die fighting for that piece of sand?
Be that as it may you're overlooking one major difference between Vietnam and Syria. The US final withdrawal from Vietnam was due to the Paris Peace Accord. Trumps' withdrawal from Syria comes NO formal peace accord no exit strategy no resolution of any kind. All he's doing is running away and leaving it up to the partner nations who are still there to figure out what to do.
