Remember, Iran is a signatory nation in the Treaty on Non-Proliferation of Nuclear Weapons. This allows them to pursue nuclear energy and other peaceful objectives.
Yet Iran is pursuing nuclear weapons technology:
The U.N. atomic agency has received new and significant intelligence over the past month that Iran has moved further toward the ability to build a nuclear weapon, diplomats tell The Associated Press.
They say the intelligence shows that Iran has advanced its work on calculating the destructive power of an atomic warhead through a series of computer models that it ran sometime within the past three years.
Why would Iran agree to real limitations on their nuclear weapons work in a new agreement when they have treaty obligations to refrain from nuclear weapons work right now?
And why would we believe future Iranian guarantees when they fail to live up to existing agreements?
There will come a day when we must deliver an ultimatum to Iran to halt their nuclear weapons work and verify it or it will come to war. Failure to issue that warning will mean Iran gets nuclear weapons.
I worry that day has already passed.
