The Irish literally did kick the UK out and carve a piece back for themselves in 1937, which is around the same timeframe we're talking about Israel in the Middle East. That's why Ireland is an independent country from the UK, and they're still in the EU while the UK isn't. So, er, yes, I suppose by my argument, it was valid for the Irish to do so. Great point on the parallel there.

(I think you are possibly misunderstanding what "Mizrahi" refers to. Mizrahi Jews are native to the Middle East and never left and were living there at the time of Israel's founding, as they had been for thousands of years.)
