Kerry is truly nuts if he brings these historical matters up in more than a passing reference. He may broadly denounce reviews of history, claiming that they only open old wounds, but he is crazy if he says anything about his personal history (e.g., "It's unfair that I am attacked, while you men were not").
I would think most of his talk will be making empty promises ($$$), after thanking and praising the veterans for their service.
I don't know what he is going to do, but he is going to pull some stunt and attempt some way out of this, because the stonewalling is not working.
He is crazy or at least obsessed that he is a war hero. I bet he says something about knowing what it is like to be in combat and that he proudly fought for his country. He will strike up a unity theme, but Kerry just can't resist alluding to his personal experience in Vietnam. He is, after all, a VFW member, which GWB is not.
