Look, man, if I was them I would want several of the World's biggest nukes RIGHT NOW. You know why? They've got the biggest battle fleet in the World (US Navy aircraft carriers) right off their coastline. They're already BEEN attacked all through the 1980's.   They've got the US Army and Marines positioned now in Iraq and Afghanistan...on either side of their borderline. They've got USA spy planes flying over their territory, doing an inventory on their defence positions and checking out juicy targets...as was done over Iraq before the last war.

The only thing that can possible protect a country under such circumstance is:

1. immediate and total surrender to foreign occupation and domination by the USA (not gonna happen!)

2. several nuclear weapons with immediate launch capability.

Wake up for a moment, pinch yourself, and remember that Iranians are human beings! Just like you. They want to survive and be in charge of their own affairs. If they had a few nukes, no one would invade them.

Of COURSE they want to build some!
