Iran Nuclear Program Now Advancing. American Response?

It looks like the Iranians are continuing thier nuclear enrichment program - despite promises they would end it.

Iran Said to Renege On Nuclear Promises

While allegations of Iraqi WMD programs were dubious at best, it has long been known that Iran had an advancing nuclear program.

It appears that Iran's continueing push to develop nuclear weapons has been largely ignored. Iran is already capable of producing nuclear fissle material. Only thirteen other countries have this capability, and seven of them are nuclear. They now have all the material needed for building a nuclear weapon. Also, Iran has developed a missle capable of reaching as far as Israel.

According to Atlantic Monthly, Paksitan and Iran have been working together for over a decade through a "secret nuclear-weapons-co-operation agreement." Iran has also made use of the international trade in nuclear scientists - sending 17,000 Iranian students abroad for nuclear training, and importing so many North Korean scientists that they built an exclusive resort.

Given that we just waged war over what Bush is now calling "weapons of mass destruction related programs" how do you think the Iranian nuclear program fits in? Should America react, and if so, how?
