President Barack Obama on Monday defended the U.S. strategy to defeat ISIS, saying it needed to be intensified not altered. In a press conference at the end of the Group of 20 meeting in Turkey, Obama said the strategy will work but will take time. Obama said it would be a mistake to put large numbers of U.S. ground troops in Syria and Iraq. Obama said the G-20 has agreed to new steps to stem the flow of foreign fighters in and out of the region.
