If they were capable of sober and clear thought I don't think they would want atomic bombs.
==================================================================
If ANY country that has them were capable of sober thought, they should not want them, either.
The US military wants nukes because they realize that the US could never win any land war in Asia against China without using nukes. We have been defeated in Asia once, and certainly neither Iraq nor Afghanistan shows any promise of victory in that either nation will vote with the US and Israel on any local issues in the UN.
Iran feels threatened by the US. And this is perfectly logical, as the US has armies on countries bordering both the east and west borders. The US has overthrown Iran's elected government once before, and many US leaders want to do it again. The only thing preventing this is that Iran has a population of 77 million.
Exactly how close the US has actually come to nuclear war is not clear. I don't think there was ever much of a threat.
