When I was TAD with the Marines EOD twenty years ago (quite a fun bunch, I can assure you), WMDs were solely ABC. Even goodies like Daisy-cutters, large ANFO and similiar weapons did not qualify as WMDs. I figure EOD specialists ought to know. I still don't like the WMD label being applied to everything under the sun that goes bang. The term thusly loses it's definition.
As far as Americans waking up to the threat, well, I fully expect one of our larger cities to be a total wipe before that happens. And when (not if) it does, you'll see a lot of "woulda, shoulda, coulda" finger-pointing. And we'll still have the usual amicus hostis apologists running around mewling their usual tripe. Assuming they aren't part of the ash-heap, of course.
