The purpose of this paper is to lay emphasis on the remarkable role of the United Nations in combating the global issue of terrorism. The United Nations Charter, 1945 aims to maintain international peace and security. To achieve this tremendous goal, the United Nations along with the peaceful partnership of Member States needs to address the alarming issue of terrorism. This work significantly takes into considerations the various attempts of the United Nations to combat terrorism. This includes the legal instruments to prevent terrorist acts, various resolutions passed by the United Nations Security Council and the United Nations General Assembly, UN Global Counter-Terrorism Strategy and Counter-Terrorism Implementation Task Force. The four pillars included in the UN Global Counter-Terrorism Strategy have been dealt with in detail. Counter-Terrorism Implementation Task Force and its thematic Working Groups work for implementation of the Counter-Terrorism Strategy. These attempts by the United Nations are fruitful in knitting all nations together. In report A/71/858, released in 2017, the Secretary-General, António Guterres explores the outstanding role of the United Nations. The United Nations’ approach to addressing terrorism is very thorough and noteworthy. But, there is an urgent need for a comprehensive Convention to develop to clearly give a clear pathway to fight against terrorism. Terrorism, is an international problem cannot be solely solved by the United Nations. For this, all nations need to come together and develop strong judicial machinery. They should join hands with the United Nations system to support education, equality, human rights, and awareness.
