Why do Jewish young people feel that they should control the land of Israel?

Here is your answer :)

So the reason Jewish people base their claim to the land of Israel are these four premises: 1) God promised the land to the patriarch Abraham; 2) the Jewish people settled and developed the land; 3) the international community granted political sovereignty in Palestine to the Jewish people and 4) the territory was captured in defensive wars.

I hope this helps you:)
