I don’t think your comparison works because Israel does not have a comparable anti-war movement that the US had during the Vietnam War. In fact, if the media is to be believed, there has been enthusiasm on the part of Israelis to take part in the fighting.

Wouldn’t that only make vietnam vets more blameworthy? There was a whole movement against it and they still chose to not give up their home/family and choose exile even when it was less stigmatized to do so.

Your comparison doesn't work because Vietnam War didn't start with Vietnam attacking USA, holding many hostages, the group leading the charge having religious ideology viewing Americans as second class citizens as well as people to ethnically cleanse, all while bordering USA.
