I am saying that if the state said something is legal, it should not then prosecute people for having done it while the state was saying it is legal. If you have a problem with what another state is doing (and you are a state), then you should apply diplomatic/military pressure; I do not know what other recourse you have. In this case, what was done is illegal under international law, and was illegal under international law at the time it was done, so people can be tried in international court without ex post facto concerns. I am one of those people who disagree with the Nuremberg trials. If something atrocious happened, but was legal, then we should make it illegal and accept the fact that some people got away with doing horrible things.
