text: In May 2010, Lula and Turkey's prime minister Recep Tayyip Erdoğan negotiated a preliminary fuel swap agreement with the Iranian government on uranium enrichment, that ultimately failed. The preliminary agreement that they presented to the United Nations was at odds with what the International Atomic Energy Agency and other countries viewed as necessary actions to stop Iran from obtaining weapons grade materials. And within hours of signing the agreement, Iran did an about-face and announced that it would continue to enrich some uranium. U.S. Secretary of State Hillary Clinton said Brazil was being "used" by Tehran.  The UN Security Council ultimately rejected it when permanent member country representatives argued that “the swap proposal negotiated by Brazil and Turkey would leave Iran with enough material to make a nuclear weapon,” and that “Iran intends to continue a new program of enriching uranium to a higher level.” Pulitzer Prize winning journalist Thomas Friedman wrote: "Is there anything uglier than watching democrats sell out other democrats to a Holocaust-denying, vote-stealing Iranian thug just to tweak the U.S. and show that they, too, can play at the big power table?" Moisés Naím, editor in chief of Foreign Policy magazine and former Minister of Trade in Venezuela, said "Lula is a political giant, but morally he has been a deep disappointment." In 2010, in addition, Brazilians largely disagreed with Lula as to how to handle Iran and Iran's nuclear weapons program. While Lula opposed additional international economic sanctions against Iran, of the 85% of Brazilians who opposed Iran acquiring nuclear weapons, two-thirds approved of tighter international sanctions on Iran to try to prevent it from developing nuclear weapons.
