In September 2014, Bilal Y. Saab, Resident Senior Fellow for Middle East Security at the Atlantic Council's Brent Scowcroft on International Security, and Michael S. Tyson, Marine Corps Senior Fellow at the Scowcroft Center, predicted in a simulation exercise (for results, see "ISIS War Game: The Coming Stalemate") conducted at the Scowcroft Center's Middle East Peace and Security Initiative that the most likely scenario was a military stalemate. They also realized that such a stalemate was not stable. Since the conclusion of the first war game, ISIS's regional attacks have increased in scope, lethality, and level of sophistication, as evidenced by its military and terrorist operations in Libya, Saudi Arabia, Egypt, and Lebanon.
