Iran and Obama discuss Nukes.

A conversation between President Obama and Ayatollah Ali Khamenei discussed the Nuclear program in Iran.

 The Obama administration and its European allies are preparing a new offer for negotiations with Iran on its nuclear program, senior administration officials say, but the conditions on Tehran would be even more onerous than a deal that the country’s supreme leader, Ayatollah Ali Khamenei, rejected last year. Iran’s reaction, officials say, will be the first test of whether a new and surprisingly broad set of economic sanctions is changing Iran’s nuclear calculus. As recently as last summer, senior officials, ranging from the C.I.A. director, Leon E. Panetta, to the chairman of the Joint Chiefs of Staff, Adm.Mike Mullen, predicted that while the sanctions would hurt Iran, it was unlikely they would prove sufficient to force it to give up the major elements of its nuclear program.
