Conservatives in the Iranian Parliament say they are working on a resolution of their own to counter the economic pressure aimed at forcing Tehran’s hand and prevent Iran’s negotiating team from agreeing to production limits on nuclear fuel. Like many in Congress, they would be happy to see the current negotiations collapse.

The resolutions in the United States Congress would choke off more of Iran’s oil revenue if the talks in Vienna do not end in an agreement by the end of June. The proposals in the Iranian Parliament would require Tehran to deploy centrifuges that can enrich uranium more efficiently than ever.

One measure, described with glee by a senior parliamentary official over the weekend, would increase the production of a form of the nuclear fuel that is just shy of bomb-grade material.
