For experts that follow Iran sanctions, the bill is a good step toward tightening the noose on Iran's economy but not enough to bring the Iranian economy to its knees in a way that would compel Iran's leaders to abandon their nuclear ambitions.
"This bill is a major step towards economic warfare against the Iranian regime. It closes significant loopholes and tightens U.S. sanctions in key areas including shipping. But Iranian nuclear physics is beating Western economic pressure," said Mark Dubowitz, executive director of the Foundation for Defense of Democracies. "We need to skip intermediate steps and go to comprehensive economic warfare. Everything must be prohibited unless permitted, and the only transactions that should be permitted are small purchases of Iranian oil and the sale of humanitarian goods. Destroying the regime's energy wealth is the best way to avoid a military confrontation."
"What exactly is this going to do to get the Iranians to the table? This is the time for the mallet, not fine-needle surgery," said Danielle Pletka, vice president of the American Enterprise Institute. "We see this as a do-or-die moment. Our purpose is not to have effective sanctions; our purpose is to bring them to the table to give up their nuclear ambitions."
The House Republican leadership has signed on to the compromise, although the question remains whether all of the Senate GOP caucus will go along. One congressional aide knowledgeable about Iran sanctions defended the compromise.
"We'll inevitably hear voices this week who say this could have gone further on x, y, or z. But it's important not to make the perfect into the enemy of the good, and this sanctions bill is good -- very good, in fact -- and by passing it, Congress can make a real difference," the aide said.
Defense Secretary Leon Panetta defended the administration's action on Iran sanctions today during a stop in Tunisia. "I think what we all need to do is to continue the pressure on Iran economically and diplomatically, to take the right steps here to negotiate," he said.
