I'm very sceptical of any type of international "law".
From my perspective, enough countries have nuclear weapons to ensure that no country will run wild with them.
Increasing the number of countries that have them, especially a country like Iran....is simply asking for trouble. I'm not personally interested in "equal rights".
Oh, and Antonio: You're becoming quite a Neocon
I don't think anyone is arguing that Iran ought to have nuclear
weapons (I'm definitely not). However, Iran does have a right (recognized by the United States) to peaceful nuclear
power, and we should deny this to Iran just because we don't like their government. We're really in no position to decide which states should and should not be allowed to have peaceful technologies.
As an aside, I find it ironic that the people who are so gungho about nuclear power in the United States are some of the strongest opponents of letting Iran develop this power for its own citizens.
