Earlier quoted context omitted.
I'm not sure what Iran having nukes does other than change the power dynamics in the Middle East to one where Israel can't bomb civilians with such impunity... North Korea and Pakistan has nukes.
I think most people in the middle east will tell you that Iran acquiring nuclear weapons is bad. As I'm sure you're aware, they are a major supporter of terrorist organizations.
Discussing what terrorism is, in this context, is rather complicated. Especially speaking as a Brit, and knowing rather a lot of other dates, such as 1917.
