(AP Photo/Charles Dharapak, File) (Newser) – President Obama will meet with Russian President Dmitry Medvedev tomorrow to discuss a successor to the recently expired START pact on nuclear weapons. The meeting, on the sidelines of the Copenhagen climate conference, isn't expected to yield a final accord. Both leaders, however, have pledged to eventually sign a replacement for the 1991 treaty, which expired earlier this month, reports Bloomberg. The main snag is how to monitor new ICBMs, notes AP.
