Terrorism is often construed as a well-thought-out, extreme form of violence to perceived injustices. The after effects of terrorism are usually reported without understanding the underlying psychological and social determinants of the terrorist act.

This special paper helps to explain the psychosocial perspective of terrorism in Pakistan that leads to violent radicalisation. It identifies the terrorist acts in the background of Pakistan's history, current geopolitical and social scenario. The findings may also act as a guide on addressing this core issue.
