President Obama isn't in that 33% .
Via Pew Research:
The public supports tough measures – including the possible use of military force – to prevent Iran from developing nuclear weapons. Nearly six-in-ten (58%) say it is more important to prevent Iran from developing nuclear weapons, even if it means taking military action. Just 30% say it is more important to avoid a military conflict with Iran, even if it means that country develops nuclear weapons. These opinions are little changed from October 2009.
Republicans are far more supportive of using military force to prevent Iran from developing nuclear weapons than are either Democrats or independents. Moreover, a majority of Republicans (62%) say the U.S. should support an Israeli attack to stop Iran’s nuclear program, compared with just a third of independents and Democrats.PEW:
