It would be more appealing to know who is doing the suing? Probably not Kerry as he is a public figure?
It would be my hope that JFK is investigated to determine if he used his political office to acquire an honorable discharge.
I'm guilty of not verifying Mr. O'Neill's claims. I just donated some money to the Vietnam Veterans Legacy Foundation as I did to the Swift Boat Veterans for Truth in 2004. I found John O'Neill to be a compelling figure and tried to see/hear every interview he gave during the 2004 campaign -- and he never disappointed.
