Adib Shishakli
Atassi received senior Iraqi leaders in Damascus, including Crown Prince Abd al-Illah and Faisal II of Iraq, for technical discussions on union. This angered Syria's emerging military strongman Adib Shishakli, who claimed that the Hashemite family of Baghdad should have no jurisdiction over Damascus. Shishakli demanded a change in course, yet Atassi remained adamant and refused to submit to military pressure. In response, Shishakli arrested Atassi's Chief of Staff Sami al-Hinnawi, a People's Party sympathizer, and several pro-Iraqi officers in the Syrian Army. He then demanded that one of his right-hand-men, Colonel Fawzi Selu, be appointed Minister of Defense, to ensure that pro-Iraqi influence in Syria remained under control.
