I suspect they know who they are already. Not every run-of-the-mill terrorist camp has a 100 pounds of enriched uranium in the pantry. After news of this, you can bet they'll redouble their efforts to hide the "stash".
Of the 24, how many are in Iraq and Iran??? More than a couple dozen I'd guess. With most the rest in North Korea. Funny how that axis keeps showing up in things.
