The key here is that Palestine did not accept the fleeing refugees. Instead their Palestinian brothers, (so-called) used them as human hostages against Israel. The so-called “Right of Return” was a key element in the Zionist claim to get back the land of ancient Israel against the Palestinians. So Abbas knew what he was doing and he dropped the request of asylum when Israel recognized the ploy and denied the request. Sadly, the downtrodden and homeless Palestinians are the hapless pawns in this mid eastern game of politics.
