I don't think anyone feels comfortable with Pakistan having nukes either.
‘This is not peace, it is an armistice for 20 years.’ (Ferdinand Foch. After the Treaty of Versailles, 1919).
Pakistan doesn't have the same ability to lock down the country as the truly totalitarian Iranian regime enjoys.
Very different, many ways. Pakistan's existence does not and cannot excuse the creation of another North Korea. "It could be worse" and "look over there" are not legit arguments, even if they might make us feel better sometimes.
As for Iran specifically, it hasn't invaded another country in hundreds of years, it hasn't given terrorists chemical weapons to attack Israel when it's had the chance for a while now and it consistently says that it will attack Israel only if Israel or the US attacks it first.
Exactly. They fear tipping the scales and they will continue to have the fear with nuclear weapons.Plainly speaking, of course they desire regional hegemony but have been limited and relatively restrained in their ability to act. Why? Because they fear both conventional and asymmetric counter stroke. Why aren't they, and why didn't they pump guns and agents to the Houthi in Yemen? Why have they been so placid with regards to the Shia demonstrations and clashes in the Eastern Province and in Bahrain? Why have they been so keen to keep a tamp on Hezbollah and to limit their arms flow to Hamas? It goes on, and on. Because they fear tipping the scales too far and incurring an American or Gulf led counter stroke. Either conventionally, or through the arming of paramilitaries in Iran, or direct action against Iranian proxies.
And this is where the problem is. You think that nuclear weapons will stop them from being afraid. However, it won't. The reason they are afraid now is because they know other states are bigger and more powerful. When they get nuclear weapons, other states will still be bigger and more powerful. Moreover, the history of nuclear weapons does not support the notion that Iran will just go crazy with their nukes.With that fear obviated by nuclear security Iran would be much more aggressive, and much more capable and unconstrained to use its 'deadly swam of mosquito forces' in all forms. They could surge weapons to Hezbollah and see them used on Israel or the Lebanese government with impunity, knowing retaliation against them will be tremendously limited. They can send military formations to Iraq without fear of the spillover crossing back into Iran. They can arm the Shia in the Eastern Province with explosives, and send weapons and IRGC agents to Yemen, why? Because the ability to act against them has been more or less taken off the table.
