Is the world getting ready for a 3rd world war?

Look i didn't come to this though easily. It came to me two weeks before the elections. I didn't feel good with trump nor Hilary. My thinking was we are getting close toward a nuclear war. So soon after the election, I started to research about wars, why and how it started. Found out some interesting things. Some things was obviously in war, like mankind been at war with each other since we existence. Over the last 500 years been very challenging for humans. Some experts think major wars runs in cycles, like in American history. The American Revolution, the Civil war, ww1 and ww2. A theory is a major war happens every 70 to 80 years. Base on this, we are right about there. According to Graham Tillett Allison, is an American political scientist and professor at the John F. Kennedy School of Government at Harvard, we are entering Thucydides trap. There is other reason why I'm thinking we are getting closer toward war each day. Some examples of what is happening in today world, is Russia and Nato's playing major military war games. Russia and the US is clearly not going to be on the same page in the world views, and that is leading to mistrust, and a heavy load of tense. Then we have China playing a major factor in today world. First China is clearly not helping the US with trading, nor controlling the North Korea crisis. China say one thing about the North, and then do the other. Now we have India and China threatening war with each other. The US also have a big issues on the islands china made in the south china sea. We have a other thing not favoring the US, and that is Russia and China are in a military and economies partnership. Both countries now having good relationship, Obviously this is not a good sign for the US. The world also have the middle east needing a excuse to go to war, and what a better way to go if the big countries go first. The way i see it, the world is preparing to go to war. The war could happen soon or it could happen within 2 years to the next 10 years. Sure we had the cold war, and nothing happen, but we need to know why nothing happen then and that is because Russia and the US knew the red lines. Now the red lines have moved, and we really don't know where there are. Now there is more player in the game with alot power and these red lines haven't been set. SO with no new rules, the game of war is so much more dangerous. The reason why I'm writing this is to let people know what we are in for, and it is pretty scary. Hope I'm wrong about this. Let's hope the world leaders will think before they act.
