I read in the koran that in the last days the jews will be abel to go back in a mingeled crowd. so why the hyostile attitude towards israel if it is the will of Allah.

We do not understand what you are referring to in the Qur'aan. However, any information about the future in the Qur'aan and Ahadith is termed as Taqdeer (pre-destination). Taqdeer actually refers to the perfect, absolute and conclusive knowledge of Allah Ta'ala. It does not refer to Allah Ta'ala making people committing acts against His orders, thereby absolving people from their evil acts due to them being helpless. Surely Almighty Allah Ta'ala' will not order helpless people to do anything beyond their ability. Allah Ta'ala has ordered the jews to be submissive to His orders but they (the Jews) were consistently defiant to His orders. Allah Ta 'ala therefore repeatedly condemns them for their disobedience. In brief, the evils of the Jewish people , the Zionist movement, the establishment of the illegitimate state of Israel, etc., etc., are evils well known by Allah Ta'ala , and accordingly condemned by Allah Ta'ala Himself. The purpose of Allah Ta'ala informing us of the evils of the Jewish people is surely to hate the evils perpetrated by them.
