Is the U.N. an Out-of-Date Institution?

In another class I am taking this semester, I learned in more detail as to why the U.N. is set up as it is. The U.N. is an international institution that was created by the winners of the Second World War. The Five Permanent members on the U.N. Security Counsel  are the United States, the United Kingdom, France, China, and Russia. As the years have progressed, a lot has changed, and many powerful countries have waned and risen, but the same five members have stayed in there powerful positions with no new positions added.
In that class, we talked about how the U.K. is not as powerful as it used to be without its colonies. the U.K. was once the empire in which the sun never set because of how wide its reach was. There were colonies in Africa, Asia, North and South America, and in Australia. By the end of World War II, all of its colonies became independent and the majority of its influence on the world was lost. The country had been reduced to just a tiny island in the north of Europe. France was quickly defeated at the beginning of World War II and part of its citizens collaborated with the Nazis until the country was liberated by operations carried out on D-Day and the weeks after the initial beach assault. China, Russia, and the United States were rising powers by the end of the war, but Russia as the Soviet Union collapsed by the end of the Cold War. As of right now, both France and the U.K. hold their status as a symbol for the victors of World War II.
The European countries of France and the U.K. should be replaced with Germany, which now has the largest economy in Europe. Germany became much stronger after it became unified towards the end of the Cold War. It has a lot of power in the European Union. if any European country wants to do anything, they need Germany's support or else it will be very difficult to get many other countries the help pass anything through. On the U.N. Security Counsel, the continent of Africa is not represented at all. African countries like Egypt or South Africa should be represented in one of the five impermanent security counsel seats so that way the Americas, Europe, Asia, and Africa are all equally represented on the counsel.
The U.N. has done a lot to help maintain peace and fight issues plaguing the world today. It is not a perfect institution by any means. It will probably be almost impossible for any of these changes to happen because no one likes giving up any sort of power. the more likely option is that there becomes more permanent added to the counsel. this will make it more difficult to get anything to pass through the counsel since there would be an increase of countries with veto power. The way the U.N. system is now is that Europe is over represented and Africa is severely underrepresented. Until something is fixed, there will not be an equal representation of all the regions of the world.
