How did the united nations avoid world war 3?

Answer 1

World War 3 hasn't necessarily been averted. Especially in these days of almost instantaneous communication and rapid transport, there is always a potential for global conflict of serious magnitude.

On the positive side, the same aspects of modern life that make world conflict more possible also help to alleviate the possibility. Negotiation, cooperation between nations, and diplomacy all help to lessen political tensions. Those are probably the primary ways by which problems are averted.

On the negative side, there still exist many political tensions in the world which are difficult to solve. There are severe religious and political tensions in the Middle East, and historically, always have been. The problem of nuclear proliferation grows more severe as other countries advance technologically and aspire to join the ranks of more powerful nations.

The "Cold War" was a distinct possibility for a "World War 3" with the added threat of massive use of nuclear weapons. Aside from time and careful negotiations (often worked out behind-the-scenes), restraint on the part of the most powerful world leaders seemed to prevent or at least mollify the possible escalation of tensions. Also, most in power recognized the probable horrible outcome of a nuclear Holocaust for humanity in general. So, despite the power gained by having nuclear capability, the result of actually using that power has been self-limiting, to some degree. There would be not much point in subjugating another population if, in the process, you destroyed your own.

Some conflicts are dampened by smaller wars, such as the war on terrorism in Afghanistan. Preventing radical factions from gaining power, or delaying or degrading their ability to do so, can prevent larger conflicts from happening. So, sometimes war itself can work with diplomacy and negotiation to prevent a larger conflagration from occurring.

Answer 2

Better communications and diplomacy. For instance, the US President and Soviet Premier had a direct telephone hotline which enabled them to talk during times of emergency. Also, the United Nations while imperfect proved itself more strong and effective than the League of Nations. And there was the concept known as Mutually Assured Destruction which maintained a balance of power, as a third world war most likely would have been fought with nuclear weapons, and there would be no winners.

Answer 3

Formation of United Nations and ban the use of Nukes after 1964.

Answer 4

Conflicts Such as Iran-Iraq conflicts, continuous korean conflicts can be major causes for retaliation and formation of treaties which will lead to ww3.
