I'm sorry, I just don't see the logic behind allowing more aggressive States to have nuclear arsenals when Iran has attacked no one in modern history. I've been to Iran, met its people, stayed in their homes etc and they are not the stereotype Sword swinging, carpet riding fanatics they're made out to be in anti Islamic US Media.
Iran has the highest literacy rate in the Islamic world including its women. There's no better way to understand the truth about a country & its people other than going there
Many foreign governments support "Terrorist" groups & Proxy Armies throughout the Region, Israel, for example supports ISIS, al Nusra & al Quaeda in Syria. Hezbollah is currently fighting ISIS etc & only considered a "Terrorist" group by 3 countries in the world & considered by many to be a Humanitarian / Social Service Group especially by the S. Lebanese who have repeatedly suffered numerous Israeli massacres, invasions & bombardments.
Is it the overall spread of Nuclear weapons you oppose, the existence of all Nuclear weapons or only opposition to Iran's acquiring Nukes you support?
