Former Chairman of the Joint Chiefs of Staff Gen. Richard Myers (Ret.) joined Maria Bartiromo on "Sunday Morning Futures" today to share insight on the fight against ISIS in Iraq and the global threat posed by radical Islam.

"The basic threat that we faced in the late 1990s and then of course after 9/11 really hasn't gone away," Myers said. "It ebbs and flows. It's right now pretty strong in the form of ISIS. If ISIS goes away, my guess is something else will take its place."

"You need a pretty long-range strategy to deal with something like this and, I think, a comprehensive strategy."

Myers said that the strategy must have an element of force to defeat ISIS militarily, but it also must include dealing with the things that lead people to jihad.

He added that it will be a "multi-generational" strategy, which would necessitate the help of many friends and allies, primarily countries in the Middle East.

Myers said that this will definitely require boots on the ground, the brunt of which can and should be provided by the Iraqis and other Middle East allies.

How do you get Middle Eastern countries involved in the fight? Bartiromo asked.

Myers asserted that it will require good diplomatic relationships, encouragement and pressure.

"I think our relationships with Egypt, with Saudi Arabia and so forth need to be strengthened to help them through it," he said.
