the Jews do not drive us to this war, as this will be a war of extermination and a momentous massacre which will be spoken of like the Mongolian massacres and the Crusades". According to Yoav Gelber, the Arab countries were "drawn into the war by the collapse of the Palestinian Arabs and the Arab Liberation Army [and] the Arab governments' primary goal was preventing the Palestinian Arabs' total ruin and the flooding of their own countries by more refugees. According to their own perception, had the invasion not taken place, there was no Arab force in Palestine capable of checking the Haganah's offensive". King Abdullah I of Transjordan King Abdullah was the commander of the Arab Legion, the strongest Arab army involved in the war according to Rogan and Shlaim in 2007.

Jordan's undertakings not to cross partition lines were not
