WWIII?

I don't think there will be a WWIII in our lifetime. There are lots of wars going on and there will be lots of wars in the future, but I don't think there will be a war as large as WWI and WWII. There hasn't been a world war in over 60 years so I don't see any reason for one to break out now. The United Nations is now a big organization which is doing its best to keep peace. During the first two world wars there was no such organization keeping peace and the League of Nations was just a failure because there weren't too many countries that joined. The United Nations plays a big part in keeping the peace and tying together the countries so that they can talk over problems and not go to war. Nobody likes war and I'm sure if a war did break out, it would end quickly before too many countries joined.
Also, now, unlike 50 years ago, people keep traveling and moving to different countries. Before, there weren't many nationalities in one country and if there were, they all wanted freedom. Now it's different because if people move to a country other than their own country, it is because they want to. People from all different parts of the world are friends now. There isn't a high chance that many countries will go to war on a large scale. Before, countries all wanted power, colonies, fame, etc. but now they get money and power by building their economy, and not trying to take over other countries. We don't have people like Hitler who want to take over the world. Lastly, if some countries were having a problem, they wouldn't go to war to fix it because now we have technology much better than the technology we had before and communication is much better. This is why I don't believe there will be a WWIII in our lifetime.
