Washington (CNN) -- The efforts by leaders of Turkey and Brazil to broker a nuclear deal with Iran reflects growing dissatisfaction with the traditional world order in which the United States is the only superpower, which they view as outdated and unjust. And their intervention on the Iran issue reflects a growing perception among many countries that the United States is unable to resolve international conflicts alone. The visit this week to Tehran by Turkish Prime Minister Recep Tayyip Erdogan and Brazilian President Luiz Inacio Lula da Silva was a rare show of personal, high-stakes diplomacy by a pair of world leaders.
