The land of Israel which is the lullaby of three major world religion is under the deadly threat. Islam and Christianity are both derived from Jewish religion. Christianity started in the very beginning of the Common Era and the Islam in VI century.
Jewish religion counts thousands of years.
The Jerusalem is the holiest city for all of these religion, but at the first hand it is the most holiest city for Jews. In addition, Torah says that the Creator Promised the land of Israel to Jews, not anybody else. Now, We can see that the Muslims are willing to destroy the state of Israel. The Israel has already yielded many territories under the Palestinian control. No, they need everything, and will not accept anything less than total control over the Jerusalem.
