Well, if New York got nuked, and I was dying of radiation poisoning, at least I'd die happy knowing Mecca was a pile of glowing sand.
Kind of selfish, I grant you. If I were a better person, I suppose I'd fold paper cranes in my last hours. But I think I'll be a little too cranky for origami.
I'd be a bit cranky too. But feelgood solutions are supposed to be the province of the liberals, not us.
I'll tell you what my reaction would be. First, if we found the country that either supplied the weapons, or sheltered/aided the group that pulled it off, we take out their capital.
Regardless of what we find out, the next thing is to take off the gloves on every government in the ME. There are governments we know aren't doig everything they could for various reasons that we tolerate right now because at least they're doing something. That would no longer be enough.
Instead, they'd all have to crackdown on everything. Immediately, and completely. Any government that didn't do so would find itself subject to a declaration of war, and taken down. If that means war with the whole region, that's what it means.
I'm not afraid for us to get our hands dirty. I just want us to be smart about it.
