Stop making excuses for what was done. I don't see you saying that to these Jews in here.
There were no excuses needed. You do realize that the past was very different: for most of human history, the
right of conquest was an accepted way of doing things. If you had the power to take land and impose your will on other people, then it was assumed that the gods — or God — approved. That is simply how people thought, and this is a historical fact.
The establishment of colonialism in Africa was, in part, driven by the desire among some Europeans — especially the British — to end slavery in Africa. They viewed slavery as barbaric and believed they were bringing enlightenment and civilization to the continent — the so‑called “white man’s burden.” Now, you can argue that slavery was already declining in parts of Africa, just as some argue it was declining in the American South. That might be true, but regardless, the abolition of slavery was one of the motivations. Of course, I admit that many, perhaps most nations, were outright cynical or opportunistic. But that is always the case in any system and in any great crusade. There are always people who join for what they can gain, whether it was the civil rights movement, the Crusades of the Middle Ages, or any other movement.
As for the Israeli–Palestinian conflict, Jewish people themselves are not the issue. The situation could, in theory, be solved through negotiations. The problem is that radical Palestinian groups are not willing to negotiate and often kill any Palestinian who tries. There
is a solution other than violence, but groups like Hamas reject it. They want the elimination of Israel — the obliteration of the Israeli people. We have heard that kind of rhetoric before in history.
If you look at the historical record, the settlements in the West Bank are a relatively recent development in Israeli history. They may have been started, at least in part, as a way to put pressure on the Palestinians to come to an agreement.
