As far as I know, he never formally renounced his US citizenship, so the argument that by serving in an army opposing the US he is not covered by treason laws is invalid. He might at best claim to have dual nationality or citizenship, but by international law that could mean he is subject to the laws of both countries that claim him (or that he claims).
I think he certainly should be tried for treason. If he really has the courage of his convictions, he should be willing to pay the price for his beliefs. Changing the subject just slightly, there was an article in the NY Times earlier this week about how a lot of the Pakistanis fighting in Afghanistan with the Taliban were sent there by charismatic mullahs in western Pakistan - who all, it seems, made quite sure that none of their own sons and relatives went off to fight. Also, the Taliban seem to have resented these foreigners and done little to integrate them into their own units. Most of the Pakistanis were poorly trained (if at all), poorly armed, given no information about where they were going or what they were doing, and were almost all abandoned when the Taliban started retreating. Poor saps. On the other hand, they were all avid to entrench Muslim fundamentalism, anti-Americanism, and other stuff I can't stomach. So maybe they got what they deserve. Too bad the mullahs who sent them off as cannon fodder are all safe at home in Pakistan. And do you think anyone will learn anything from this? Like, maybe those mullahs aren't to be trusted in all things (or in any thing) after all? Naaaah. Tom Beck "I always knew I'd see the first man on the Moon.
