WASHINGTON (Reuters) - President Barack Obama, grappling with a poor economy and slumping approval ratings, faces problems on a larger stage this week at the United Nations, with challenges to his leadership in the Middle East and questions about the U.S. role in the world.
Obama will seek to reassert his diplomatic credentials in an address on Wednesday in the cavernous U.N. General Assembly hall, where he has been warmly received in past years.
