The Afghanistan War took a heavy financial toll on the Soviet Union during the 1980s. Similar to the American invasion of Afghanistan in the early 2000s, the Soviets realized it to be very difficult to defeat an enemy when an invading force attempts to restructure another nation's government or eradicated a non-political force (such as the Mujaheddin or al-Qaeda). <span />
For Germany the treat of Versailles dealt them a heavy hand. They were imposed land, economic and military restraints as well as forced to pay a great deal of the reparations cost for countries like France. Whom during world war one had received heavy damages.
