Refugees from what?

Nobody flees from home, country, family and friends without good reason, so why are there so many refugees? Part of the reason lies in things that the West did or failed to do in the past. There would not be so many refugees from the Middle East if the US and UK had not invaded Iraq in 2003, setting in train Sunni-Shia wars, ISIS, the revolt in Syria... And there would not be so many from Africa if the West had continued its 1960s policies of support for family planning, rural clinics and the health of mothers and infants. Yet it still goes on; the sale of offensive Western and Russian arms fuels several wars, and Trump has reduced funding for various humanitarian programmes. The refugees of the future are already being prepared.
