LOL at “EMP attack!”.
Atomic air burst would give EVERYONE cancer.

Actually that is what I am thinking too. Their atomic bomb does not have to be accurate. If it goes off some vicinity of a big city, the resulting fallout would impact many people with life-threatening health problems. Besides, who wants to live in a city near fallout zone? Technically, it may be safe after several months, but people won't be near it for at least a decade. The whole city would become a ghost town. That is a serious widespread economic damage from which it is difficult to recover in a short time.

No, not true. An atmosphere blast produces the least fallout, and elevates the blast damage furthest away from the ground (away from the cities and stations that can be damaged.)
