In the throes of a crippling, violent insurgency, Dagestan is Russia's hotbed for Muslim extremism, and its jihadists have been behind many high-profile terrorist plots around the world. Alleged Boston Marathon bomber Tamerlan Tsarnaev spent six months there the year before that deadly attack. To understand why so much terrorist activity originates in the region, and to see firsthand what Tsarnaev learned during his stay, Shane Smith heads to Dagestan to follow in terrorists' footsteps.

The Israel-Palestinian conflict is one of the best-known and longest-standing conflicts in the world. Although the United States publicly advocates a two-state solution, it also remains Israel's biggest ally. While significant American support comes from a strong, wealthy Jewish lobby, in terms of sheer numbers, Evangelical Christians in the heart of the Bible Belt are Israel's strongest supporters. Thomas Morton uncovers the rationale behind Evangelical support for the Jewish state.
