Ok, so circumstancial evidence and IAEA inspectors have been saying that the nuclear weapons programme has been halted since 2003. The breach they are talking of is enrichment of uranium. That doesn't necessarily mean WMDs.
You can ignore the fact that Iran won't be using WMDs ever. You see, even the arab countries in the close-by region don't want much to do with Iran.
And finally, how come I am the one with the tinfoil hat? I don't go on and on about weapons programmes that are rumored to be true by unnamed "experts" and US officials. I also don't ignore the fact that Iraq was invaded over WMDs it did not have.
You may need to stop being biased really.
