Stockpirate is on to something.
What is the M.O.(modus operundi) of a weasle like Kerry? Get in as good as you can with your bosses so that you can get attaboys.
What did Kerry do? Got in as good as he could. Wrote up flowery after-action-reports, making KERRY'S superiors look really good.
What has Kerry shown in the past 30 years? A BRAZEN ability to take completely diametrically opposed positions (War hero to anti-war peacenik to public warhawk).
The documents seem to indicate that Kerry re-uped for 6 years, although Kerry won't reveal that.
Here are two totally opposed thoughts on that:
1# - Stockpirate is correct. Kerry was acting as the mole in the anti-war VVAW movement. That would explain where some of that info was coming from. In that case, Kerry would TOTALLY betray he fellow anti-war comrades. But, so what? Kerry had already shown that he would betray his fellow comrades who were still in Vietnam.
2# - Kerry was arrested and charged with treason or conduct unbecoming. Fullbright and/or other powerful senators talked the Navy into covering it up. Part of the agreement was that Kerry had to re-up for another six-year hitch to keep him quiet. Notice that about 1972, his anti-war diatribes went away.
There are speechs and such that have Kerry listeda s a national leader well in to 1972.
I think it is tinfoil hat time.
