High percentages of US voters believe that Iran is actively pursuing production of nuclear weapons, Israel will attack Iran and the US will join Israel in military action, a new IBOPE Zogby survey finds. Similarly large percentages of respondents believe attacks on Iran could lead to high fuel prices. Voters are split on whether the US should take military action against Iran if it has credible evidence Iran is building nuclear weapons. The IBOPE Zogby interactive survey was conducted from February 17-21.
