Recently President Trump imposed trade tariffs on Chinese steel. As a reaction, the Chinese government imposed tariffs on its import from the United States. The worldwide trade war is fueled by this.
Earlier the European Union imposed tariffs against Chinese agriculture and cheap electronics. A prime example is the tariffs on Chinese garlic. So the garlic goes from China to Norway and from Norway to the European Union. Although the European Union says they support free trade they are really just protecting inefficient industry who are going to die.
Soon the world is stuck in a global war. Not because countries wish to have a war, just because the quickly formed alliances are bringing the world towards a war. The reason this could go wrong is we just see in Syria. Now there are rockets launched and we inform the opposite side what we will do.
Due to the alliances and instability from the move towards the east are all government leaders thinking more and looking at what the best way to move forward is.
But on an economic side is the world already in a world war. A world war which will have no winners, only losers.
