"...As more Arab leaders come against Iran's nuclear program, more of their citizens come to support it...""

The UM poll ... Pretty significant. (and Obama's numbers way down with ordinary Arabs):

On Iran's potential nuclear weapons status, results show another dramatic shift in public opinion.

While the results vary from country to country, the weighted average across the six countries is telling: in 2009, only 29% of those polled said that Iran's acquisition of nuclear weapons would be "positive" for the Middle East; in 2010, 57% of those polled indicate that such an outcome would be "positive" for the Middle East.
