More so, Arab nationalism emerged due to the shared language, Islamic religion, as well as the history of the Middle East region and so Arab nationalist, hoped for political cooperation via the Arab League. Notably, Arab nationalism developed at the end of the eighteenth century to oppose European colonialism in the region. Arab nationalist radicals perceived Israel as their enemy not only because of their injustice against their colleagues in Palestine but also Israeli’sclose relation with the western imperialist aspirations especially concerning oil reserves towards the region.The Arab nationalism was, therefore, a significant cause of the Arab-Israeli conflict since it enabled the Arab nations to have a common enemy and this gave them strength to fight against Zionism as well as the western power. Ideally, the Arab states are supposed to join forces and remain unified towards the achievement of the common goals, opposing Israel. However, in practice, this is not always the case as their relations are more determined by conflict as opposed to cooperation. Notably, Israel is one of the leading factors contributing to the disintegration of the Arab nations and this is why all Arab states highly oppose it. Despite their differences, Arab states remain united in opposing Israel because according to them, individuals from different Arab states including those living in Palestine form one nation but Israel interfered with the sacred rights of this nation.
