Watch Two Sneak Peeks from This Week's 'VICE' on HBO Episode About the Islamic State

So far this season, VICE has investigated climate change, police militarization, dangerous legal highs, and more. This week, we are devoting our entire episode to an investigation into the Islamic State and the situation in the Middle East that spawned them. In our first segment, Suroosh Alvi travels to Saudi Arabia to see how America's staunchest Arab ally is faring while the Middle East fractures around it—and how the country may be fanning the flames of global militancy.

In our next segment, host Gianna Toboni travels to Europe to meet some of the young would-be fighters from Western countries who are drawn to the Islamic State's call and flock to join their self-styled utopia. Then, Toboni visits with American Navy strike pilots who are working to roll back IS's gains.

Watch VICE Fridays on HBO at 11 PM, 10 PM central, or stream it via HBO Now.
