Terrorism is one of the greatest challenges of the present world. Scholars are divided on the measurement of the effectiveness of terrorism. Consequently, the study is arguing that the effectiveness of terrorism-as a great security matter- should not be investigated from any specific objective but should be analysed from every potential angle to measure its success. For this purpose, the study has used secondary data from various sources like renowned journals, articles, books, newspaper etc. By reviewing various literatures, this study revealed that terrorist campaigns for regime or political change (which is known as strategic objective) is a conventional idea. Terrorist activities have many objectives like organizational, individual, media attention, creating panic to the civilian and so on. As a result, not only the strategic objective but also all kinds of objectives should be taken into the consideration to measure the effectiveness of terrorism. In future, deeper and comprehensive study is required to address the multi-layered objectives of terrorism to identify the better understanding of the effectiveness of terrorist activities.
