In Avi Shlaim's 2008 biography of Jordan's King Hussein. he recounts an episode from Hussein's father King Abdullah I:
One question that has continued to puzzle observers is: why did Abdullah disregard all the warnings and keep to his plan of Friday prayers in Jerusalem [the day he was assassinated]?One possible answer, which was long to remain a closely guarded secret, is that Abdullah had arranged to meet two Israeli officials in Jerusalem the next day, Saturday, 21 July 1951.The two officials were Reuven Shiloah and Moshe Sasson, who was continuing the negotiations for a peace treaty that his father, Elias, had begun.At one of their first meetings, Moshe Sasson asked Abdullah, "Why do you want to make peace with Israel?" The king replied, "I want to make peace with Israel not because I have become a Zionist or care for Israel's welfare but because it is in the interest of my people. I am convinced that if we do not make peace with you, there will be another war, and another war, and another war, and another war, and we shall lose all these wars. Hence it is the supreme interest of the Arab nation to make peace with you."
