Democratic Party U.S. presidential candidate Bernie Sanders tells a Georgetown University audience that Muslim nations should bear the biggest share of the burden of fighting Islamic State. He cites reports Qatar was spending $200 billion to host the Soccer World Cup in 2022 but providing little to bear the cost of fighting extremism in the Muslim world. Sanders says his focus in running is not on pursuing "reckless adventures abroad, but to rebuild America's strength at home." This contrasted with remarks by Hillary Clinton in New York the same day calling for the U.S. to lead the fight to defeat the the Islamic State terror network after Paris attacks in Nov. 2015, and putting forward a position that contrasts with that of the Obama administration.
