I have a quite different (and most likely biased) opinion than most people (here or in Western countries).
WWIII is already happening. The US is closing up on Russia now for more than a decade. China is growing economically but they are still far away militarily and except for Russia there isn't really another contender for the US militarily speaking.
Before 2010 the world was quite multi-polar with the US being the leader. Now, we are moving to a uni-polar world and this is of course triggering reactions both from China, Russia and countries that want to remain sovereign (ie: India, Brazil, ASEAN, etc...)
Countries not in the western sphere are already aware of this. The EU is quite aware of this too and it's going to be a loser in this new order but it doesn't seem to be able to build a politically independent force to have its own policy. Russia is the main target and they know this, that's why they are freaking out. China probably doesn't like Russia much but certainly would prefer a multi-polar world (at least until they are able to become the leader); so they'll help the Russians to slow down the West. Major other countries like India do not like China or Russia but they are concerned about the accumulation of power and inflation in the West/US hands. Smaller countries are trying to survive in this environment and feed their people either by selling their young labor for pennies, or opening their borders for rich people from the West to sun bathe.
That's the world for you, in a nutshell.
If I am to predict the future:
- Russia gets drawn in a long war with Ukraine. The US is playing the long game of starving them financially and technologically.
- China will probably collapse in a spectacular fashion. They are far from being a united country. The outcome won't be easy to predict and China is huge. It is possible this will happen without much disruption to trading lines.
- Europe/Euro/Schengen will end sometime in the next 10 years. Some European countries will be back to third-world status.
- With the fall of the Euro, the US dollar will become the ultimate currency. The US will be able to yield enormous influence all over the world.
