It is the worst sentence I have ever heard of. It demonstrates an unseriousness about the war and the stakes involved.
Andy hyperventilates a bit here, I think. The guy is a driver. It seems to be acknowledged that he wasn't capable of planning or leading, he's just a guy who did low level jobs. A servant, essentially. By Andy's lights Hamdan provided
material support to our enemies, [...] actually protected bin Laden and transported weapons for al Qaeda,
all of which is, I assume, literally true. But it's a silly, bad faith exaggeration of Hamdan's apparent role. Does every grunt in Bin Laden's organization deserve life behind bars? What purpose does that serve, except to feed Andy and his fellow travelers' thirst for revenge, even when it's overblown and mostly inappropriate. Get your hands on Zawahiri, then try for a life sentence. Five years in GTMO ought to be enough for a the guy who changed Bin Laden's flat tires.
