Another evil intention I can recall along this thread is the "neutron" bomb. The idea being, produce a nuclear weapon that has a extreme radiation pulse during detonation but generates no long lived nuclides. Detonate over enemy territory, everyone dies from radiation sickness from the detonation, then you can move in and all the infrastructure is still in place. Not much development ever took place, considering such a thing could only ever be an offensive/invasion weapon.
