An additional aspect to the aftermath of the war was the Palestinian refugee crisis. By the end of the war, there were approximately 720,000 refugees living in camps in Syria, Jordan, Lebanon, the West Bank, and the Gaza Strip. Although much of this can be attributed to war-time fear, some historians, like James Gelvin, assert that Israeli policy in Plan Dalet partially contributed to this crisis. The policy, which encouraged Israeli forces to seize Arab property in Jewish territory, exacerbated the refugee issue. As of 2015, the right of these refugees to return to their former homes or to receive reparations remains uncertain.
