Americans show substantial pessimism about Iran and its nuclear program. Six in ten believe that Iran has decided to try to produce nuclear weapons and is actively working to do so. Nine in ten believe that it is likely that Iran will eventually develop nuclear weapons.

If Israel goes ahead with a military strike against Iran’s nuclear program and Iran retaliates (but not against American targets), only one in four favors the US providing military support for Israel and only 4 in 10 favor the US providing even diplomatic support. Few would support open opposition. The most popular position is for the US to take a neutral stance.
