Almost two-thirds of respondents in a new Wall Street Journal/NBC News poll believe it is in the nation's interest to confront the group, known as ISIS and as ISIL, which has swept through Syria and northern Iraq. Only 13% said action wasn't in the national interest. The poll was conducted as US President Barack Obama pepared to address the nation on the eve of the 9/11 anniversary on his strategy for action against the Islamic State in Iraq and possibly in Syria too. In a meeting with leaders of Congress, US President Barack Obama said he would welcome their support to demonstrate to the world that the US is united in defeating the threat from ISIL. But, he stressed, he doesn’t need congressional authorization for such action.
