They are talking here about unleashing the classic "clean bomb". Nation-states and sociopaths have struggled for thousands of years with the problem that when they unleash war, the infrastructure they wish to take control over is destroyed in the fighting, so even if they gain the "territory", they don't gain the material benefits. For decades, they've talked about a bomb that would kill the people but keep the infrastructure intact so the winners could walk in and take it.

And here it is. These shots are the way to kill the population without losing the infrastructure. Satan is feeling very pleased with himself right now.
