Interesting fact about Jews in Koran

What I find most interesting is that the Koran mentions the children of Israel repeatedly yet Islamists deny the existence of the right for a Jewish state. Aren’t they contradicting the holy Koran? If they are playing pick and choose verses while isolating from context game, let me point out some verses using their own game.

Just for an example is Surah 2 verse 47: “O children of Israel, remember my favor that I have bestowed upon you and that I preferred you over the worlds."

In fact the Torah is the book of God used by a number of his prophets as evidenced by  Surah 5, verse 44: “Indeed, we sent down the Torah, in which was guidance and light. The prophets who submitted to Allah judged by it for the Jews as did the rabbis and scholars by that with which they were entrusted of the scripture of Allah, and they were witnesses thereto.”

Denying the right to a Jewish state is not justifiable within Koran.
