He did not specify what actions the Bush administration will be taking. His reaction came after the Vienna-based nuclear watchdog IAEA said it had received a letter from Tehran saying it would resume nuclear fuel research next week and President Mahmoud Ahmadinejad said that Iran would not step back on its decision to resume nuclear fuel work.
In terms of trying to draw a line around something being pure research with respect to enrichment activities, (that) is not something that were going to buy, and I dont think the international community will either, Mccormack said, adding the Iranians have really done, sort of, a bob-and-weave on this issue. They have been seeking to extend out discussions, not really commit to whether or not they are going to negotiate in a serious manner. And, frankly, the patience of the international community is not infinite on this issue because its a serious issue, Mccormack noted. iran is trying to pursue nuclear weapons under the cover of a peaceful nuclear programme. We dont think that that should be allowed to happen and I think you wont find any disagreement on the fact that Irans obtaining a nuclear weapon would be destabilising, destabilising to the region and destabilising to the world.
He said that the US view is that if Iran takes any further enrichment-related steps, the international community will have to consider additional measures to constrain Irans nuclear ambitions.
