As per agreement Iran hands over its uranium to Russia, rendering it incapable of making nuclear weapons. And yes, this is Obama's fault.

For the first time in nearly a decade, Iran doesn't have the materials needed to make a nuclear weapon -- even if it wanted to. 

U.S. Secretary of State John F. Kerry announced Monday that a Russian container ship has hauled away almost all of Iran's low-enriched uranium -- the fuel required to build nuclear warheads and atomic bombs. The handover fulfills one of the biggest provisions of the July accord struck between Tehran and a U.S.-led coalition known as 5+1. 

"One of the most significant steps Iran has taken toward fulfilling its commitments occurred today, when a ship departed Iran for Russia carrying over 25,000 pounds of low-enriched uranium materials," Kerry said in a statement. "I remain so proud of our team in achieving what was truly one of our most important accomplishments of 2015 -- ensuring that Iran's nuclear program is exclusively peaceful going forward." 

Tehran has long said it's had strictly peaceful intentions with its nuclear program but was willing to make the agreement and cede to atomic oversight to make that purpose clear to the international community in exchange for desperately-needed economic relief.

Of course the conservatives will find a hundred things wrong with this deal but the fact that Iran has done this, and that it has been verified by inspectors, is unprecedented.

And it just removes one more boogeyman that the Republicans can use to scare the American people into voting for them.

Which, by the way, is perhaps the main reason they are so adamantly against his deal.
