And that's the point I was originally making - that if we take the episode as written, the Commander would have to have been talking either about internal strife, or then about the old war with Earth. Both of which are possible insights into what the writer was thinking, although the odds are that he did not actually put thought into these curious lines.
Of course, other episodes open up new possibilities in addition to the above two. But the idea of the Commander being a veteran of the old Earth war remains intriguing. The guy on screen looks a hundred years old, sharp, for a Vulcanoid - as we learn in "Journey to Babel"!
But perhaps he has aged less than Sarek because he isn't suffering from the early symptoms of the Bendii syndrome, and is in fact a hundred and thirty years old, having fought Earth for a decade and been idled ever since.
