Biden's withdrawal from Afghanistan will likely spark a new refugee crisis. As the US withdraws its troops without a peace deal in place, the Taliban has gained control over large parts of the country. This will cause many Afghans who assisted US forces or hold liberal views to feel threatened. They will likely flee as refugees. Previous US wars in the Middle East and South Asia have already displaced over 37 million people. When refugees flee Afghanistan, nearby countries and Europe will again see a large influx of refugees seeking asylum, as occurred during the Syrian refugee crisis of 2015-2016. The withdrawal from Afghanistan could lead to one of the world's worst humanitarian crises.
