Nope UN Resolution 242. Jordan grabbed the area during Israel’s war of independence (1948), annexed it in 1950, then Israel did its six-day thing, conquering the territory, and the UN said “nope neither of you can keep it it’s still Palestine”.
Much of applicable law in Palestine is Jordanian law, though: It’s a modern system and culturally appropriate enough, so why replace it when you can tinker. Not that it matters much, Israel is applying its own martial law to the whole area because it didn’t annex it but occupy it, which in principle should make the settlements illegal under Israeli law but you know only democracy in the Near East and all that.
You’re trivialising Nazi rule.
And that’s precisely why noone in Germany is listening to you. I can only surmise that you’re a Hasbara agent trying to paint the Palestinian cause in a bad light.
