Seeing the Forest for the Trees
There's no question that it was extremely fortunate that this multi-nation plan was exposed when it was, even though it's likely that either Iran or North Korea have already managed to create enough fissionables for a few weapons. It would have been far better if it had been exposed earlier, but an additional ten year delay would have been catastrophic.
There is equally no doubt at all that those revelations were a direct consequence of the war the US is prosecuting, most especially in Iraq. It is by no means clear that without our war there would have been a significant chance of the plot being exposed until too late.
