So does he have some good reasons for these nightmares, or is he just again coopting some about Vietnam veteran-lore into his act?
It sounds like his wife thinks he has a good reason, although she may or may not know what the reason is.
Why would she talk about this in front of a reporter, though?
People don't normally talk that way about their spouse in public unless there is a lot of animosity there. I discount the idea that it was staged, since I don't see how Kerry benefits from such talk. This was in 2002 anyway.
So I'm uncertain how to interpret this interview.
