Some people would argue that Iran with weapons grade uranium could reasonably increase the chances that 50,000 Americans will die in the next 10 years by more than 1 in 10,000. That suggests the US could reasonably kill 5 Iranians to deal with the threat. However, Iran would respond to such action which suggests a more limited response such such as planting a virus is reasonable as long as the US can get away with it.
PS: That's how these people think, rare events vs lot's of deaths = covert and deniable action.
