As 1990 rolls around, all of the countries experience overpopulation problems. As this happens, countries continuously attack other countries for more land, making the entire world a large battlefield and forcing hundreds of thousands of people to flee.
Meanwhile, many countries such as Germany has been overtaken by extremists, you ousted the leaders by assassinating them and destroyed the German military by placing hundreds of bombs. The new government holds an iron fist over Germany and hates peace.
