4 Ways President Obama Is Trying to Sell the Iran Deal

A look at the president's arguments for making the Iran deal.

Here’s a look at the main ideas he’s been pushing as he tries to rally support:

1. Danger

The president has warned, most pointedly during a Wednesday speech at American University, that opponents of the deal are pushing the international community toward a war with Iran. “The choice we face is ultimately between diplomacy or some form of war -- maybe not tomorrow, maybe not three months from now, but soon.”

2. Logic

Another point the president has made is that his foes over the nuclear debate have not presented a reasonable alternative to the plan reached by the members of the P5+1 international negotiating team. “They will put forward arguments that, you know, after a few minutes, can be shown as illogical or based on the wrong facts, and then you ask them, ‘All right, what's your alternative?’ and there's a deafening silence,” he told NPR in an interview that will air Tuesday.

But many Republicans will say they have suggested alternatives; chief among them, keeping pressure on Iran via international sanctions until they give up more concessions than they are now.

3. Science

Once the deal was solidified, the White House dispatched Energy Secretary Ernest Moniz, a nuclear physicist, to help sell the deal from a scientific perspective. And it’s a point that the president has continued to hit in public appearances.

“The overwhelming majority of experts — nuclear scientists, people who are expert[s] on Iran — support this deal because they understand that by making sure Iran doesn't have a nuclear weapon, we won't have to worry about a lot of other countries in the region trying to keep up and get their own nuclear weapon,” he said in an interview with the website Mic.com.

The White House also played up a letter composed by 29 leading U.S. scientists, many of them Nobel laureates and experts in nuclear weapons and arms control, sent to the president over the weekend. They called the deal “technically sound, stringent and innovative … that will provide the necessary assurance in the coming decade and more that Iran is not developing nuclear weapons.”
