According to AP:
Most Americans surveyed in a poll say they do not think any country, including the United States, should have nuclear weapons.
The AP/Ipsos poll results show that
opposition to proliferation is high, with two-thirds (66%) reporting that no country should be allowed to have to have nuclear weapons. Concern over the nuclear issue is also evident in Americans' fears about possible future nuclear attacks. Majorities believe that in the next five years a terrorist attack using nuclear weapons is likely (53% total likely) and also state it is likely that one country will attack another country with nuclear weapons within the next five years (52%).
