Since the attacks of 9/11, terrorism has emerged as a serious concern for national security. Both the United States and Pakistan have and continue to experience the scourge of terrorism and strive to grapple with it in a manner that is compliant with their constitution.

This work attempts to analyze the jurisprudence of the United States Supreme court and the Supreme Court of Pakistan and examines whether the former has impacted the interpretation of the latter.
