Part of the problem is that the Bush administration has been in no great hurry to mete out justice, military or otherwise. Consider the speed with which the German and German-American saboteurs in the Ex Parte Quirin case were caught, given a military trial ( by special tribunal if I recall), sentenced, had an appellate review by SCOTUS and then duly executed. Now consider Khalid Sheikh Mohammed, who is just now, perhaps, facing the initial steps in applying military justice.

Yes, in the wake of 9/11 there were overriding intelligence concerns with interrogating ranking members of al Qaida in American custody but five years? That speaks to an avoidance of justice as a policy with the unwelcome necessity of meting out death sentences to some of the illegal combatants and acquitting and/or paroling others. The inability of senior administration officials to settle differences of policy, authority and jurisdiction between the Departments of Justice, Defense, State and the CIA are also visible in the cases of Hamdi, Moussaoui and Padilla.

A streamlined, very tough but impartial and constitutional system to try illegal combatants for breaking the laws of war is very " doable" - if the political will exists to carry it out.
