In their actions to date, the governments of North Korea and Iran threaten to take us down this dangerous slope. We respect their rights as members of the community of nations. I've said before and I will repeat, I am committed to diplomacy that opens a path to greater prosperity and more secure peace for both nations if they live up to their obligations.

But if the governments of Iran and North Korea choose to ignore international standards; if they put the pursuit of nuclear weapons ahead of regional stability and the security and opportunity of their own people; if they are oblivious to the dangers of escalating nuclear arms races in both East Asia and the Middle East -- then they must be held accountable. The world must stand together to demonstrate that international law is not an empty promise, and that treaties will be enforced. We must insist that the future does not belong to fear.
