The US-Russia nuclear arms deal that Obama is slated to sign April 8 signals a modest, but significant, step forward.
China signals it will consider a new UN resolution on Iran sanctions, in a bid to pressure Tehran to verify that it is not trying to develop nuclear weapons. Is China expecting something from the US in return for its cooperation?
Speculation has continued to rage in South Korea as weather has delayed recovery of 46 sailors still missing in the Cheonan ship sinking. South Korean minesweeping vessels arrived at the site on Sunday evening.

A salvage ship and three other American vessels are on site to help with search and recovery operations after the South Korea ship sinking in the Yellow Sea, US Navy officials say.

Presidents Kennedy, Reagan, and now, Obama all envisioned a world free of nuclear weapons. The US-Russian START accord, announced Friday, is a next step in that direction, experts say.
