Sorry who's home was conquered when? The British Empire might not have colonised Palestine but they did conquer it and allow settlers in with the intention of forming a state for the Jews.
The Ottoman Empire conquered the area from the empire that existed before them, who conquered it from an empire that existed before them, all the way back to prehistory
Roughly it's,
ancient Egypt
ancient Israel
Persian empire
Macedonian empire
Hasmoneans
Roman Empire
bunch of random caliphates
Ottoman empire
British empire
Israel
There was never any political entity known as Palestine until Israel sought to create one.
I never intended to disagree with that, but my point was that just because the nation of Palestine didn't exist 500 years ago does not mean that the people who today we call the Palestinians hold no claim to the land.
And it certainly doesn't mean that Israel has a claim to it, does it? There was no State of Israel before 1948, either, what claim did they have to it?
War is the only way that matters! Small consolation to the colonised and conquered. Do we not aim to hold ourselves to higher standards in the modern age? Imagine if our world leaders decided that the only thing that mattered is defending land through war!
Clearly they don't, otherwise we wouldn't have anyone trying to mediate conflicts, anyone calling for ceasefire in Gaza. Do we just accept Russia invading Ukraine? If Russia flattened the country and took over, do you think that would be justified? Don't get me wrong, I don't think there would be a procession of countries willing to invade and take it back, but that isn't because Russia would have claimed the land, it would be because they fear for their own people's lives.
Why, if you think every country in the world is only respecting borders because of military power, doesn't the US just take over? They certainly have tje military power to back up an invasion of almost any country on the planet.
