Last week, the United Nations reported that the number of people fleeing the war in Syria
had surpassed 4 million, making it the worst refugee crisis of our generation. The sheer scale of the Syrian exodus becomes evident through a comparison with several other conflicts that have taken place since 1991.
Even though the chart below focuses on selected conflicts since 1991, Afghanistan
has been in turmoil far longer than that. Since the Soviet invasion in 1979, an estimated 2.6 million Afghans have been forced to flee their homeland while the genocide in Rwanda resulted in 2.3 million people being displaced.
