You need to get your facts straight, then you won't make this false analogy between Britain/Ireland and Israel/Palestine. Israel occupies the territories in question because Israel was invaded from them. Britain was not invaded by Ireland. Palestinians (Hamas) and their supporters (Iran) have denied Israel's right to exist as the homeland for the Jews. The Irish never denied Britain's right to exist as the homeland for the British.
