A large number of Arab and Western researchers have dealt with the Crusades, but there are certain aspects that desperately need analytical studies, with an objective vision that is far from being influenced by narrative methods or being driven by the studies written by Westerners, some of which were devoted to serving their colonial interests in the region, as this is evident in One of the studies concluded that the policy of peaceful coexistence is the only way to serve the common interests between the Crusaders and their neighbors, and if the opposite happens, this leads to harm and harm to both parties, so this study comes to clarify the dimensions of the narrow regional policy adopted by the rulers of Damascus for the survival of the Crusaders from On one side and the leaders of the Islamic Resistance Movement on the other hand, and the negative effects it has had on the conflict between Arabs and the West. This study also aims to clarify the political and military weight that Damascus would have represented. Had it been employed to confront the Crusader aggression, the balance of power would have been outweighed in favor of the Islamic camp.
