I see few if any cases in your link where the U.N. has returned refugees from 50 years ago. There comes a point where people need to quit trying to undo history and get on with their lives. Note that one of the categories in those reports is asylum.
I don't think that people who left a country because they hoped its government would be overthrown should in general have a right of return, and I certainly don't think their descendants should have one. Backing the wrong side in a war has consequences, and people need to learn to take responsibility for the consequences of their own choices.
What percentage of the refugees from the late forties are even still alive?
