United States President Barack Obama called for the nations of the world to work together in a speech at the United Nations General Assembly on Wednesday. “Now is the time for all of us to take our share of responsibility,” he said.
"Those who used to chastise America for acting alone in the world cannot now stand by and wait for America to solve the world's problems alone,” he added pointedly.
Obama said UN member states had fallen short in addressing the world's problems. Among the issues he called to address were genocide, “protracted conflicts,” nuclear proliferation, and global warming.
