BRUSSELS (Reuters) - The United States will strengthen its military presence in Syria to prevent Islamic State fighters from accessing oil fields and revenue, U.S. Secretary of Defense Mark Esper said on Friday, the latest twist in President Donald Trump's policy on Syria.
Trump has been softening his pullout plans for Syria after a backlash from Congress, including among key Republicans, who say he enabled a long-threatened Turkish incursion against Kurdish forces in Syria who had been America's top allies in the battle against Islamic State.
