I came across an article who was written by a Nigerian Based in American named Mr. Adeyemo Akintunde: "The Classification of IPOB as a Terrorist Organization: The Buhari Administration and Military Correctly Classified IPOB as a Terrorist Organization, Legally Speaking—a Primer on Terrorism"
After reading the article, i have to come up with an article in response to the above article because there is no single definition of what terrorism means, so it's possible for someone to disagree with your definition of terrorism.
