The World Before The End

Before the invasion of the Chimera in 1945 every nation will sign a peace agreement in the decades before. Germany, France, Britain, China, Japan, the US, the great nations will be at peace. But Russia is left out, the Russians' fear of European anti-imperialism, forces Russia to cut off all contact with the outside world. A large stone wall barbed with wire is erected along the borders called "The Red Curtain" which dominates the Great Wall of China for span and width. The economy in each city will be blooming just as history had, technology will advance especially warfare.
