When half the people polled were simply asked what they thought of “the international nuclear deal with Iran,” only one-third of respondents approved.
The other half of respondents were asked a slightly more descriptive question about “the international nuclear deal aimed at preventing Iran from developing nuclear weapons.” Those respondents said they approved of the deal by a 10-percentage-point margin, 39 percent to 29 percent, with one-third unsure.
However, that variation pales in comparison to that in other surveys conducted the week before Trump announced the US withdrawal from the deal.
A CNN/SSRS poll stated: “The United States and five other countries entered an agreement with Iran aimed at preventing Iran from developing nuclear weapons,” and then asked respondents their opinions of the deal. They said by a 34-point margin that the US should not withdraw from the agreement.
