Secretary of State Hillary Clinton at the ASEAN Ministerial meeting in NYC about President of Iran's speech to General Assembly: -

"The international community continues to have serious concerns about his country's nuclear program. As President Obama told the general assembly, America wants to resolve this issue through diplomacy, we believe there is still time and space to do so, but that time is not unlimited and that's why the US will do what we must to prevent Iran from obtaining a nuclear weapon...If we ease the pressure or waiver in our resolve, Iran will have less incentive to negotiate in good faith or take the necessary steps to address the international community's concerns."
