"doing what is needed to make the world a genuinely safer place."

What, you mean like holdin Iran to it's obligations under the NPT?

No, I mean like negotiating with Iran as equals rather than rejecting their offers to negotiate so that we can fabricate a justification for using nuclear weapons against them as we are working on doing now. The reason Iran is beefing up their defensive capabilities is because they know we want to attack them. They tried to negotiate and we responded by rejecting their offer to negotiate, and putting them on our axis of evil list instead. The US has a history of attacking other countries, and it is behaving belligerently toward Iran. The Iranians have every reason to feel threatened by the US.
