94 Insurgents killed, at latest count. The local village had been evacuated prior to the attack, no reports of civilian casualties.
It would be super if we were not in Afghanistan. Whatever we do is unlikely to change anything there. It sucks for the people who remember when the country was more like this-

But I don’t think there is much that we can do to bring that back, at least from a military standpoint. My personal suggestion would be to leave them pretty much alone. If they start opening more Osama Bin Laden™ Terrorist Training Camps, we can bomb them from orbit, just to be sure.
But, our forces are there, and someone decided that they are required to fight the insurgents in that valley. This method seems to have been chosen by General Nicholson to achieve that mission. It had the desired effect. The bomb had been in Afghanistan since before the election. It was manufactured years ago. I bet Trump never even heard of it.
