John Kerry Can Help Heal Our Vietnam Wound

When John Kerry either irresponsibly slandered our Vietnam vets in 1971 (my belief) or told truth to power (as others believe) he created, almost single-handedly, a festering wound, as Mark Steyn points out. I propose a simple strategy for Kerry to handle this. Either show his proof that his 1971 testimony was true, or admit that he engaged in McCarthy like tactics by making nebulous false charges against a large group of unpopular Americans without any proof. If he cannot do the former, because he does not have such proof, the only responsible course is for him to do the latter, and vice versa. These choices may be seem impossible now, as they would hurt his election chances, but they would still be the right thing to do. My questions: Are they perfectly possible November 3rd? If Kerry loses? If he wins?
