Your Points notwithstanding, -Nuclear stuff from they or any other Foe would kill and injure far more than just 3,000 in one (actually 2) of our buildings, -or a few hundred in but a few aircraft. As you've made mention to.

They've more than a few times, -have publicly claimed to aim to get some Millions of us, -in another go.

I guess your point holds, that thats still a minority, -next to our 300 million population. But thats still Far More than the 3,000 and 300(?) that you give via example. Even you, -via your own Reasoning, -have to be at least that much more concerned over it! And hopefully at least that much more Mentally (I mean "Giving Thought to") and Materially Prepared for such possibilities, -however Near or Remote.
