For most of the palestinian "refugees" their homeland is were they born, which is outside Israel. All those born after 1949, they are refugees only because the UN defined them as refugees, unlike any other children of refugee all over the world. Palestinians, or should I say, Arabs who are looking for invading Israel, should stop dreaming of pushing the Jews away to the sea. Wherever they are (in Israel, Jordan, Egypt, Lebanon, Syria, US, ...) they should stop being "refugees", who still dream to destroy the jewish presence, but being human being looking for building their future where they are (whether it is in Lebanon or US or Turkey ...). Bottomnline: Be positive, build a future, instead of complaining all the time and try top get others' help to keep being negative and try to detroy the others. This is would be a durable peace. Israel has been waiting for Arabs to want peace since ever, and is still waiting.
