> Germany and Japan also got to keep their countries in the end.
Germany was split in two for many years. Ultimately they were able to keep their countries because the occupation forces were successfully able to largely de-radicalize those countries.
> What guarantees do the Palestinians have that they'll get to keep Gaza and not have it be overrun by Israeli settlers (who are already wreaking havoc in the West Bank)?
I suppose that would depend on the surrender agreement and whatever agreements are subsequently put in place, but the settler issue differs significantly between Gaza and the West Bank for various reasons. For example the issue of religious sites is a much bigger issue in the West Bank, there has been little desire amongst Israelis to settle Gaza compared to the West Bank. The security issues in the West Bank tend to also be more problematic due to proximity to major Israeli cities.
