In the middle east, Iran is considered a serious enemy, and is widely detested. A nuclear armed Iran would immediately lead the rest of the middle east to pursue their own nuclear weapons program.
It is detested because Iran is Shia and the other countries around them are Sunni. The cause is religious, not "we don't like them because they are bad".
Countries without nukes get victimized by countries with nukes. If you haven't noticed this pattern yet, there's not much hope for you.
