Welcome to the forum. Since you're so concerned about truth, stick around and learn a few things.
The truth, I believe is that Kerry's conduct was worrisome to his superiors and he definitely used the war to further his political career.
He did not agree with any part of it, yet participated and did his best to create a war record.
Very strange behavior IMO. Very strange indeed.
In fact, I would call it what it is, dangerous and self serving. Certainly not the kind of behavior we expect from a candidate for Commander and Chief.
