Also, what number of drones. At why point does a swarm become a WMD?

To me, it’s more about intelligence than numbers. You could have a single rocket but if it’s smart enough to evade enemy defenses, that rocket could level a city.

Only if that rocket had a nuclear bomb on it. You'd be surprised how not powerful individual bits of munitions are. Sure a 2000 pound bomb sounds scary. But they work really well against point targets. Cities are not point targets.

How could a non-nuclear rocket do that?

You'd need an awful lot of them - London had about 500 hits by German V2 rockets which didn't have any appreciable impact on the course of the war.
