Seems to be delusional, senior political office in the US often does that to you.
He also seems to have been rather active on the behalf of Vietnam veterans who have been rather forgiving of the Walt thing. That's not surprising, ducking into a deferment was what most officer class folks did.
In 'Nam, Gordon was attached to the 199th Special Needs Forces regiment, motto: "We're as rare as rocking horse sh1t". Rumours that he spent the entire war picking his nose and claiming expenses while sitting in Saigon's only Church of Scotland cathedral are unfounded. He did, in fact, lead his entire platoon up a particularly VC infested swamp known to the yanks as 'Sh1t Creek'. The whole platoon was killed except for Gordon but he successfully blamed the fiasco on Yank friendly fire. It's thought that this experience formed the basis of his administration of the UK economy up until 2010.
Gordon was invalided out of the forces with a Purple Fart just as things got really bad. His medical records are still sealed but he's thought to have suffered the worst case of nappy rash ever seen by the US Army Medical Corps.
As we know they both did particularly well in civvy life, particularly Gordon who saved the world some time around 2009.
