Do not try to paint it as if they were poor innocents who've fled the land after Israel has started a war with them and chased them out.
They started a war with Israel, yes, a war, in order to destroy, yes, destroy the Jewish state.
They should have been killed, I have no mercy for war starters and their supporters, they caused a lot of bloodshed and that is their punishment.
Also, on a side note, the ones who've fled the area are not the only ones who count as 'refugees'.
Their sons count as refugees as well, and so are their grandsons and their great grandsons and so on.
Get them all together and that's some millions of refugees, if Israel lets them in, as a democracy, it will be directly causing its own destruction.
No nation would ever do that, no matter how much you're going to whine about poor war-starters who've fled their lands.
