Iran Nukes under control?

Why sure. The Euros have it under control.

Last month, envoys from Britain, France and Germany offered Iran a deal that included a light-water research reactor if Iran pledged to abandon uranium enrichment and related activities. In a subsequent round of talks that finished in Paris on Nov. 6, a tentative agreement was reached, according to representatives from all sides.

Now a research reactor if it is large enough (40MW thermal) is a good tool for making plutonium. Even with a smaller reactor it just takes longer to acquire enough plutonium.

And this helps how?
