Part of Obama's Nobel Peace Prize's legacy: Russia invades Ukraine

President Obama is a weak player on the international scene. Which is why the world is falling apart. The Islamic State is fighting to take over Syria and Iraq. Iran is still trying to build a nuclear bomb. And yesterday Russia invaded Ukraine.

A powerful America means a more stable world. Obama seeks the opposite--and the world is a more violent place, despite his being awarded a Nobel Peace Prize a few months after becoming president.
