my understanding is that there were not serious nuclear programs in these facilities, which does open the question: what was down there?
whatever it was, the united states just spent a lot of money on a very sophisticated attack that amounts to a show of overwhelming force. it sends a message to everybody that the anericans still see themselves as the superpower, until further notice.
the russians know what was down there. my guess is that, whatever they say, they're glad it's gone, too.
this poses minimal threat and minimal harm, as it is. the danger is somebody miscalculating in overreaction, but i think that is unlikely.
so long as that's it, we'll have to keep wondering what they actually did, but that should be the end of it. i'm more concerned about opposition forces on the ground.
