The way I looked at it was most of the draft dodgers were probably people I wouldn't want covering my ass anyway, so it's good that they left the country.
It was bad enough when all the drug-users started joining up. That's when I threw in the towel after seven years ('63-'70). We carried nuclear-tipped torpedoes, and we had guys smoking grass in the damn torpedo room! And who the heck knew what was going on the in missile control center with the door closed and locked all the time.
