<human>:  How did the events of WWII affect the global economy?
<bot>: WWII had a significant impact on the global economy. In Europe, the devastation caused by the war left Germany in ruins and caused lasting economic and social damage in the region. Additionally, it disrupted intra-European trade and created a huge demand for new machinery, foreign investment and aid. Outside of Europe, it changed the global balance of power, forcing the worldwide decolonization process and eventually leading to the establishment of the United Nations. The conflict also put a halt to international trade and led to the start of the Cold War. The global economy thus became more dependent on the United States and Japan as the main drivers of growth.
