Here is a sobering stat related by the Economist. Interpret it as you will:
Horrifyingly, although home to only 5% of the world’s population, in 2014 the Arab world accounted for 45% of the world’s terrorism, 68% of its battle-related deaths, 47% of its internally displaced and 58% of its refugees.
Surely there is no clear cut answer to the question in the title. But allow the raw numbers to sink in.
What can be done to change them?
