What's interesting is that when India and Pakistan were partitioned at the same time, there was displacement of about 15 million people. India took in the displaced Hindus living in Pakistan, and Pakistan took in the displaced Muslims living in India. Both made them citizens of Pakistan.
Israel took in the 900,000 Jews from MENA countries and made them citizens.
Only the Arab nations refused to bring in the Arabs displaced by the 1948 War for Independence.
So how come Pakistan, India, and Israel can take in their refugees and make them citizens, but the Arab countries couldn't?
