No real country will use bombs in general, or nukes in particular.
The idea of blowing up what you want to take over is something only an idiot would consider.
Hell, even the North Koreans aren't that stupid.
In fact, they probably have the sanest nuke policy of any country in the world.
"We're poorer than sh!t, but we are building nukes. Give us money, food, and oil and we will stop." (Till we need more money, food, and oil).
Second, it's egotistical, and typical American self importance, to think America will be the target.
Israel is far more likely to take an Iranian nuke, and India and Pakistan are more focused on each other.
That's one to watch, since the Chinese have been putting pressure on India's Northern border.
1st world countries f#ck each other financially.
What do you think all this Cyber war crap is about ?
No one gives a crap about "territory any more. it's all about economics.
Humanity has been fighting among itself with out break for 4000+ years, and damned little of it has been the "Clausawitzian" conventional warfare you are all so fixated on.
That and democrat treason. are why America hasn't won a war in 75 years.
