I love how people conveniently ignore that Egypt, Jordan and Syria marched over Palestine land to invade Israel during the 1948 war. No one has made huge drama over them controlling Palestine land afterwords either. It's all Israel's fault they were invaded by what, 5 nations? The day after they gained their independence.
So really those armies are the ones that invaded and took control of Palestine, Israel then defeated them and took land as a buffer against further invasions.
People conveniently forget that the catalyst to the current state of the region is the decision of the surrounding Arab states that they needed to crush Israel. They lost.
