The deeper terrorist threat might lie not just with Islamic State fighters but with infiltrated allies operating inside Syrian-controlled territory, according to Newsmax foreign policy analyst Walid Phares.
NEWSMAX -- Public frustration over the U.S. presence in Syria is growing as details emerge about an attack that left three Americans dead and several others wounded, Phares said on "Saturday Agenda."
That is "100% question that the public is asking, especially after attacks like these. The public needs to know what are we doing there? But more important is who our ally is, who has been infiltrated, and what we expect for the future," he said.
"I was able over the past three hours to get to more details that I haven't seen in the media yet. The actual attacker and the attack was not a motorcade that was coming, and then somebody attacked it.
