Americans are very concerned about Iran's nuclear ambitions and strongly support both sanctions on the Islamic republic and "direct talks" between the United States and Iran, a new poll shows. An Israel Project survey of 800 registered voters, jointly conducted by the Republican Public Opinion Strategies and the Democratic Greenberg Quinlan Rosner Research found that 81 percent believe Iran poses a "very" or "somewhat" serious threat to the United States, and 84% agreed with the statement: "Even with all the problems that America faces at home now, we must still work hard to stop Iran from getting nuclear weapons." The poll showed that 76% support the initiation of "direct talks between the US and Iran to negotiate its nuclear program," when given "a series of actions that can be taken with regard to Iran if they do not stop their nuclear program." But 81% also backed expansion of United Nations economic and diplomatic sanctions, 69% wanted an end to "all taxpayer funded government contracts with companies that do business with Iran" and 66% of respondents want to "prevent any company from doing business in the United States if that company provides Iran with refined petroleum." The margin of error for the poll is plus or minus 3.46%.
