The problem is they can't. The only ones who have the means and the ability to do this are the elites whose conduct over the years is bringing this about. You can believe they are already sending or making plans to send their children and other relatives to places like France,Spain,or other safe havens,leaving the innocents to do all the suffering and dying.
I think the point here is that we might use them to take out known stores of WMDs. If these happen to be under buildings occupied by civilians, I suspect we would send some special ops or members of the resistance in to evacuate them before the weapons hit.
