Former Secretary of State Hillary Clinton has said that the war being waged against militant fighters in Iraq and Syria is "critical" and will be a prolonged part of U.S. foreign policy.

"Whether you call them ISIS or ISIL, I refuse to call them the Islamic State, because they are neither Islamic or a state," Clinton said. "Whatever you call them, I think we can agree that the threat is real."

"I think military action is critical. In fact, I would say essential to try to prevent their further advance and their holding of more territory," the likely Democratic presidential candidate said.

She added that "military action alone" wasn't enough because there is also an "information war" to be fought.

Clinton's comments, along with those of ex-CIA and Pentagon head Leon Panetta—"I think we're looking at kind of a 30-year war"—show that "any doubts about whether Endless War – literally – is official American doctrine should be permanently erased," Glenn Greenwald writes at The Intercept.
