The irony of the situation in Iraq was this -- the U.S. probably had a far better chance to control the development of WMD's in the Middle East when Saddam Hussein was in power than it does now.
India also has had it's own nuclear program for almost 30 years now.
That keeps Pakistan in check, IMO.
But you didin't answer the original question, do you think it's okey dokey for pre-saddam Iraq and present day Iran pursuing a nuclear program.
