Just as the phony Guantanamo detainee "problem" can be "solved" by simply treating them as POWs, I recommend another equally straightforward approach to the "problem" of allegedly unlawful behavior by the previous administration. Investigate, and where called for, indict and try the various parties.

I'm not talking lynch mob here, but rather a conventional application of the legal process to the very sort of problem for which it was designed. I would include an investigation and — if warranted — indictment of the military JAG and officer corps, the latter for obeying unlawful orders (illegal war per the UN Charter to which the US is a signatory) and the former for either failure to identify and advise re the illegal nature of the Iraq war, or, should it prove to be the case, for providing legal cover for an illegal enterprise.

Again, this would not be about revenge, but rather about affirming that the law is NOT a cobweb from which the powerful are exempt, and the US is in fact– not in myth — a nation of laws.
