The country Israel was founded by people who are native to the land. Perhaps read up on the history of the area, because what you are writing is factually incorrect.
There was no country before and the area was populated by multiple different groups of people. Those people wanted to found countries in the area. There is war(s) regarding where the borders of these countries should be.
That's how almost every country in the world came into place. The only difference here is that it is taking place in a time when the whole world is watching in real time and people are much more globally mobile.
I know it's much easier and comfortable to paint a black and white picture of the situation, but it is just false...
