If the land israel is on always belonged to jews, then why did they need to come back and fight for the land?
Israel was a European invention.

Quran 2:216...
Jihâd (holy fighting in Allâh's Cause) is ordained for you (Muslims) though you dislike it, and it may be that you dislike a thing which is good for you and that you like a thing which is bad for you. Allâh knows but you do not know
Quran 9:29...
Fight against those who believe not in Allâh, nor in the Last Day, nor forbid that which has been forbidden by Allâh and His Messenger and those who acknowledge not the religion of truth (i.e. Islâm) among the people of the Scripture (Jews and Christians), until they pay the Jizyah with willing submission, and feel themselves subdued.
I own you, so, go to mommy, stupid little boy
