True, but even if we found some, or all, it could still be considered a political reason as the impotent, useless UN would not abide by their own rulings. People would still have complained that we did it without the UN, without trying to expend all political options, we were lucky that they did not use them on us and that had we had UN backing they would not have. There would most likely be other BS reasons to make it political.
Also, if we had found WMDs some would claim that we planted them.
There is really no scenario under which evidence could have been found that all opponents of the war would agree made the invasion justifiable.
