I undrestand that there's a good amount of carve outs for wartime stuff.
However, if there's any doubt about whether they even belong in the "enemy combatant" category, it seems pretty basic to allow them their attorney. Otherwise the gov't could claim you're an enemy combatant every time they want to take your rights away, and then lock you up forever.
Sure, eventually it will be overturned, but if the gov't just wants you in there for a bit then that's enough.
There's perhaps a more ambitious argument to be made here about the AUMF, what is actually a war, the classification of ISIS as such, etc. But good luck making that argument in this environment
