The United Nations Security Council's adoption of Resolution 1 established the Military Staff Committee, an essential component for the operational capabilities of the UN in maintaining global peace and security. It was seen as a foundational step following the devastation of World War II, aiming to prevent future conflicts by creating a structured forum for military cooperation among member states. This resolution detailed the Committee's role in advising the Security Council on military matters and strategic planning for peacekeeping operations. It also specified that the Committee would assist in the establishment of peacekeeping forces when called upon by the Security Council.

The Military Staff Committee was to include representatives from the five permanent members of the Security Council: the United States, the Soviet Union, the United Kingdom, France, and China. Each of these nations would contribute their military expertise and capabilities to enhance the UN's effectiveness in conflict resolution. The resolution set the tone for future international military collaboration and emphasized the need for multilateral solutions to global security challenges. The Committee was motivated by the desire to avert the unilateral actions that had characterized prior international relations and to promote a united front in the face of aggression.

As the first resolution adopted by the Security Council, it reflected the ethos of collective security that the United Nations sought to promote. It signified a shift towards a more collective approach to international military matters, in contrast to the isolationist and unilateral tendencies that characterized many nations' foreign policies prior to the UN's creation. The framework laid out in this resolution would influence subsequent resolutions and military interventions authorized by the UN Security Council, creating a precedent for future peacekeeping operations and the development of international military doctrine under the UN's auspices.
