If we got around to prosecuting all the presidents (and other national leaders) whose actions have led to war crimes being committed....there'd be a whole lot of politicians up on trial. War itself is a great crime, particularly when it's a war of choice...(as opposed to defending your own ground against a foreign invasion and occupation). Anyone has a clear right to defend his own ground, territorial waters, and air space. No one has a right to unilaterally decide to invade someone else's, just because "they might attack us one day" or "they might do this, that or the other thing we don't agree with" or "they might have or be planning to build this or that weapon which we already have so many of ourselves that we can hardly figure out how to pay for all of them".

For practicing gross hypocrisy like that, I think it would be very appropriate to put a number of our politicians (past and present) on trial. It's not a partisan matter. It's a matter of basic moral principle that goes beyond partisan loyalties.
