Not a bad thought. (Your first one: if we're throwing nukes around I suspect minefields will be the last of our worries.) The complicating factor would be how widely they can be dispersed, and how quickly they can converge. It might take more vacuum bombs than is feasible to clear even a small area.

I had another thought. There's a tried and tested method for knocking down bird-sized moving objects. So, what about shotguns? (Yes, I know they're currently banned for combat use. I think something like this would override that, at least de facto.)
