Iran could offer to halt production of 20% enriched uranium in upcoming negotiations. This “concession” would have limited impact on Iran’s ability to quickly produce weapons-grade uranium for one nuclear warhead, however. Iran would still retain the ability to resume 20% enrichment and to produce weapons-grade uranium at a time of its choosing.

The prospect of Iran achieving nuclear breakout capability is becoming more imminent. Reports this past weekend indicate that Iran has built the infrastructure needed for operating more efficient and advanced centrifuges at the Fordow Fuel Enrichment Plant.

Sanctions, diplomatic tools, and other measures have neither changed Iran’s nuclear policy, nor had a visible impact on Iran’s nuclear program. Yet, some in the United States and the international community still dismiss the looming reality of a nuclear-armed Iran.

The Iranian regime appears to have thwarted any large-scale and potentially destabilizing opposition demonstrations on the anniversary of the 1979 revolution.

Iran is at the threshold of a nuclear weapons capability. Sanctions, direct action, and diplomatic tools have neither changed Iran’s nuclear policy nor had a visible effect on the enrichment program, including the growing stockpile of 19.75% LEU.

Calling the Fordow enrichment plant a 'Potemkin' plant is grossly misleading. Unfortunately, the reality that must be confronted is much more complicated and dangerous.

Iran's recent nuclear proposal shows that it has been neither isolated nor persuaded by UN sanctions backed by President Obama.

Iran's threat to close a vital international waterway if stricter sanctions are imposed on Iranian oil exports is more than just bellicose and provocative. It is also a test of U.S. will and commitment in the Persian Gulf at a time when our role in the region is changing.
