take the hit
there are so many people in this country that, while were gung-ho for action shortly after 9/11, they are against it now, because of Iraq. The didn't get the package all wrapped up with a bow in a handful of months, so now they believe we were wrong to start. If we wind up taking pre-emptive action against Iran, these people will be screaming, in fact, they may even be able to PREVENT us from taking pre-emptive action. I think that might be best in the long run.
I think the world (and us in particular) should prepare themselves mentally, to take the hit. Tens of thousands, possibly hundreds of thousands, or even millions will die when it happens. Tragic, horrific, terrible by any human standards. But someone of these madmen may pull it off. In fact, I don't think that it will be possible to stop them. And maybe we shouldn't.
Perhaps, just perhaps, what we need to do is, take the hit, and then get back up and turn the other cheek. On the other hand, perhaps we should just take the hit, and then burn them to the ground. Not play around.
If we know who is responsible, it would be easy. But if we don't, or if the ones responsible are not a nation state, what then? We claim the moral high ground, so if we slaughter innocents (like a city), then we will be seen as no better than they.
