"They're the weakest fighting force there," Paul said of the moderate Syrian rebels, pointing to a non-aggression pact with ISIS they reached last week. "Most of the arms we've given to the so-called moderate rebels have wound up in the hands of ISIS because ISIS simply takes it from them, or is given them, or we mistakenly actually give it to some of the radicals. So the intervention in Syria has created a safe haven for ISIS and has made our problem much more difficult."
Particularly in light of the recent ceasefire, Paul assessed, the rebels' interests lie in overthrowing Syrian President Bashar Assad. "They don't really care what ISIS does," he said.
