Introduction
Globalization is the process of increasing interconnectedness and interdependence among countries through the exchange of goods, services, information, and ideas. It has been facilitated by various international organizations and agreements. However, not all organizations contribute to the process of globalization. The United Nations (UN) is one such organization that does not directly facilitate globalization.

Explanation
- World Trade Organization (WTO): The WTO is an international organization that deals with the global rules of trade between nations. It facilitates globalization by promoting free trade, reducing trade barriers, and resolving trade disputes. The WTO's main goal is to ensure that trade flows as smoothly, predictably, and freely as possible.

- International Monetary Fund (IMF): The IMF is a global financial institution that aims to promote global monetary cooperation, secure financial stability, facilitate international trade, promote high employment and sustainable economic growth, and reduce poverty. It plays a crucial role in globalization by providing financial assistance to countries, helping them overcome economic crises, and promoting economic reforms.

- United Nations (UN): The UN is an international organization that was established to promote peace, security, and cooperation among nations. While the UN addresses various global issues, it does not directly facilitate globalization. Its primary focus is on maintaining international peace and security, advocating for human rights, promoting sustainable development, and providing humanitarian assistance.

- International Bank for Reconstruction and Development (IBRD): The IBRD, also known as the World Bank, is an international financial institution that provides loans and grants to the governments of developing countries for development projects. It supports globalization by promoting economic development, poverty reduction, and the improvement of living standards in developing countries.

Conclusion
Out of the given options, the United Nations (UN) is the organization that does not directly facilitate the process of globalization. While the UN plays a crucial role in addressing global issues, its primary focus is on maintaining peace and security, advocating for human rights, promoting sustainable development, and providing humanitarian assistance. Other organizations like the WTO, IMF, and IBRD directly contribute to globalization by promoting free trade, financial stability, economic development, and poverty reduction.
