It all boils down to an analysis of what happened on Sept 11, 2001 (for that matter, USS Cole bombing, Khobar towers, WTC 1993, Marine barracks in Beirut): was it:

a/ A spike in the murder rate in NYC or
b/An Act of War.

There can be no other possible explanation to those events. If you wish to treat them as criminals, giving habeas corpus, due process etc, then they are due court proceedings. If you agree with me that those were acts of war, then only the Geneva Conventions can apply and, as the combatants involved did NOT comply with Geneva Conventions acting as lawful combatants sent by a State, they deserve summary execution. We voluntarily to spared their lives and are reaping the whirlwind.

Now our choice are send them home to countries which will torture and execute them or hold them until Islamic terror ends and the war is concluded. If this means forever, well there are worse climates. 36 have already reentered combat which is THE point of being held captive during wartime.
