New York Times: On 8 April 2010 in the Czech capital of Prague, Presidents Barack Obama of the US and Dmitry Medvedev of Russia signed New START, a bilateral arms treaty that would reduce the number of nuclear weapons in the two countries’ arsenals by more than half.

That meeting, which would have taken place today, has been postponed indefinitely after the committee’s chair, John Kerry (D-MA), agreed to Republican requests for more time to examine the treaty.
