Washington (CNN) -- It was a long summer for President Barack Obama, who for months has defended his decision not to send U.S. troops to fight ISIS on the ground in the Middle East. But lawmakers contend that in the wake of a rapidly-spreading Ebola crisis and the upcoming midterm elections, the President's commitment towards fighting the extremist terrorist organization has fallen short. Comparing the spread of Ebola to the ISIS threat against the United States, Sen. Lindsey Graham, R-South Carolina, said Sunday that he doesn't believe that the President is handling each issue with equal rigor. "The stronger Ebola gets in Africa, the more it spreads and the more entrenched it is -- the more endangered we are," Graham told Candy Crowley on CNN's "State of the Union" Sunday. "The same (goes) for radical Islam in the Mideast. It seems to be that the President is all in when it comes to Ebola. I want to compliment him for sending troops to help get ahead of this in Africa, but we have a series of half-measures with (ISIS)."Sen. Lindsey Graham says Obama "is all in when it comes to Ebola," but not ISISSen.

(CNN) Foreign policy, increasingly, is what is happening around the world while the United States is making other plans. More than five months into Donald Trump's presidency, American adversaries and allies alike are adjusting to a new era in which Washington seeks its own idiosyncratic and unpredictable "America First" path. In Europe, Asia, and the Middle East, governments are assessing shifting US priorities and in some cases seeking alternative sources of leadership and partnership in the belief that America has stepped back. Trump's unpopularity abroad is forcing leaders to consider their own political positions, before getting too close to the American President -- even if they seek to preserve Washington's still vital global role as the guarantor of liberal market economics and democracy.American adversaries and allies alike are adjusting to a new eraTrump's unpopularity abroad is forcing leaders to consider their own political positions
