How about the other way around, does it make it harder for Iran to go to war with us? Or our allies?
The Islamic Republic has never attacked one of its neighbors, so, no.
As opposed to the US, which has bombed, occupied or invaded 15 Islamic countries since 1980.
The thing was, the Iranians weren't really interested in a bomb to start with. They get sanctions relief, trade and assets returned for not doing something.
What has our "Allies" (A bunch of shitheads who cause a lot of our problems) upset is not that they have a fear of an Iranian bomb, but that IRan will be mainstreamed back into the international community.
