Partner cooperation is crucial when it comes to fighting terrorism, but it's also complex. Stephen Tankel, assistant professor at American University -- most importantly -- a senior editor here at War on the Rocks, examines U.S. counterterrorism cooperation in his new book With Us and Against Us: How America's Partners Help and Hinder the War on Terror. He and Ryan chatted about troublesome partners like Saudi Arabia and Pakistan, how young academics can be more policy-engaged, and what Stephen drank to celebrate reaching major academic milestones.   Be sure to check out Stephen's book: https://amzn.to/2JyufwJ
