"Strategic nukes? Hell no. Way too damaging to international relations and trade.
Tactical nukes? Possibly, but only in very specific instances. For example, taking out Iranian nuclear facilities... (would be justified as a preemptive nuclear strike against military-only targets). In the particular case of Iran, I would guess that the US would be able to take advantage of support from European nations that fear Iran and that have supported the US in harsh action against them, such as France."
I agree with Clancy that the political force involved in nukes renders ALL nukes "strategic weapons"

Steve Jobs has ruined this joke.
