After Vietnam, when the engineers of that debacle admitted numerous mistakes (for which they should have been tried for war crimes), military service became much less fashionable for our political caste. It was a noble cause but carried out in a reckless manner.
After the recent disasters in Iraq and Afghanistan (in which Americans died for nothing, to say nothing of the much larger numbers of the populations of those countries), I understand why people don’t enlist anymore. There will be no trials for those who send Americans off to die in (and kill in) these conflicts, and our own country is under a very real assault along the southern border with the federal gubmint refusing to lift a finger.
