Reality Check: The failure of the so-called “war on terror”

After 14 years, $4.4tn, and hundreds of thousands of deaths, has the so-called 'war on terror' made the world a safer place?

In Reality Check, Hasan exposes the failures of the global military campaign to fight "terrorism".

The Arena: What makes young men and women from the West fight for ISIL?

Britain confirmed this week that two of its nationals, who were accused of fighting for the Islamic State of Iraq and Levant (ISIL), were killed in a precision drone strike in Syria.

The British government justified the killing of Ryaad Khan, 21, and Ruhul Amin, 26, claiming the two young men were plotting attacks against the UK.

The pair are part of a growing list of young men and women from the West who leave their homes to fight for ISIL. But what drives these individuals? Is it solely religion or are other factors at play?

In this week's Arena, anthropologist Scott Atran, one of the few experts who has talked directly with al-Qaeda and ISIL fighters, debates counterinsurgency expert Sebastian Gorka on why young people from the West leave their homes to fight for ISIL.
