The big difference being that in starving, impoverishing and oppressing us, the Brits actually became the architects of their own downfall in Ireland.
So many of us were forced to flee Ireland, especially to the States, that we began to establish ourselves there. People began to realise we were not just the thick, savage terrorists the British have painted us as for centuries, but had something to offer the world. Bigger and at the time, better nations than Britain began putting pressure on them, began taking a closer look at what was going on, until they couldn't keep committing the same old atrocities they had been carrying out for so long. They didn't stop because they suddenly grew a conscience, they stopped because they knew the gig was up.
The problem today in Palestine is that there aren't better countries in a position to put that pressure on Israel. The few countries with any power today, are as morally bankrupt as Britain has always been and they stand behind the wrongdoers, not the oppressed in this and in so many other conflicts.
While the governments, the media and so many of the people in Western and powerful countries are happy to keep painting victims as terrorists or savages, and bullies as the legitimate good, defending themselves, I can't see how we ever get to a position of peace that doesn't involve the complete extermination of Palestinians as a people.
