The Vet see's history repeating itself, or rhyming at least, and knows what's eventually coming, potentially sooner than later, if things keep going the way they are. So ya, he's no doubt upset about what happened in the past to stop this, only to see it happening again. It's like going through absolute hell to supposedly beat cancer, only to have signs of recurrence.
Not only that, he's no doubt aware that based on the condition the West is in overall at the moment, that now, is not the time you want to have to fight Hitler the 2nd in WW3. The kind of people you really need to join and get dirty in that type of war, are not going to bother this time around based on the past, present, and foreseeable future, and without them, it's anybody's guess as to who comes out on top this time (assuming of course it doesn't go nuclear quickly leading to total annihilation).
He's clearly legitimately worried, and is right to say what he said. Some people never learn, and some, if not many, unfortunately hafta learn the hard way because of it.
