I don't think your "nuclear war" scenario will come to pass. The vast majority of priests are good, honorable men, as are 90% of the bishops.
A sore on the finger that hurts attracts all of your attention.
The fact that there aren't other sores on other parts of your body might go unnoticed in your focused pain.
I doubt that more than one or two bishops will resign, and that no priests, other than the perps, will leave.
