Great job by Hillary Clinton Obama hails new nuke treaty with Russia - The Oval: Tracking the Obama presidency US President Barack Obama gives an unscheduled press briefing at the White House as US Secretary of State Hillary Clinton (L) and Secretary of Defense Robert Gates look on in Washington, DC, on March 26, 2010. The United States and Russia concluded on March 26 a landmark nuclear arms treaty which imposes sweeping cuts on deployed Cold War-era nuclear warheads and missiles, the White House said. President Barack Obama and Russian President Dmitry Medvedev concluded the deal to replace the START nuclear treaty in a telephone call Friday and will sign the new pact in Prague on April 8. CAPTIONBy JEWEL SAMAD, AFP/Getty ImagesPresident Obama hailed a new nuclear deal with Russia today as "the most comprehensive arms control agreement in nearly two decades," and a major step toward his long-term goal of a world free of nuclear weapons. The new Strategic Arms Reduction Treaty cuts by about a third the number of nuclear weapons to be deployed by the United States and Russia, Obama said. It also makes cuts in the number of missiles and launchers, as well as "a strong and effective verification regime." Less than an hour after speaking with President Dmitry Medvedev, Obama said he and his Russian counterpart will sign the new START on April 8 in Prague -- the same city where Obama gave a speech last year on nuclear non-proliferation.
