"US Secretary of State Hillary Rodham Clinton said the world must respond to the sinking of a South Korean warship that has been blamed on North Korea. She met with South Korean President Lee Myung-bak at the Blue House where she confirmed the United States supported the decisions of the South Korean leadership. She also said the US would be consulting with South Korea and members of the UN Security Council on what the appropriate action to take would would be, but she declined to offer a timeline for action. ""The international, independent investigation was objective, the evidence overwhelming, the conclusion inescapable: this was an unacceptable provocation by North Korea and the international community has a responsibility and a duty to respond. The measures that President Lee announced in his speech are prudent, they are absolutely appropriate, and they have the full support of the United States.""
