Stating that their continuing hostilities are a threat to world peace, Iran has offered to mediate talks between congressional Republicans and President Obama. Irans Supreme Leader, Ali Khamenei, made the offer one day after Iran received what he called a worrisome letter from Republican leaders, which suggested to him that the relationship between Republicans and Obama has deteriorated dangerously. Tensions between these two historic enemies have been high in recent years, but we believe they are now at a boiling point, Khamenei said. As a result, Iran feels it must offer itself as a peacemaker. He said that his nation was the logical choice to jumpstart negotiations between Obama and the Republicans because it has become clear that both sides currently talk more to Iran than to each other. He invited Obama and the Republicans to meet in Tehran to hash out their differences and called on world powers to force the two bitter foes to the bargaining table, adding, It is time to stop the madness. Hours after Iran made its offer, President Obama said that he was willing to meet with his congressional adversaries under the auspices of Tehran, but questioned whether any deal reached with Republicans is worth the paper its written on. For their part, the Republicans said they would only agree to talks if there were no preconditions, such as recognizing President Obamas existence.
