 On 19 January 1957, Jordan signed the Arab Solidarity Agreement (ASA) with Saudi Arabia, Egypt and Syria which entailed those countries' financial assistance to replace the annual British aid to Jordan that ended with the abrogation of the Anglo-Jordanian Treaty in November 1956 (the treaty was officially and mutually abrogated in March 1957).However, implementation of the ASA was hindered by Egypt and Syria's inability or unwillingness to subsidize the Jordanian army, whose budget rivaled that of their own armies.Furthermore, by then, Abu Nuwar was steadily losing Hussein's confidence due to dissatisfaction with Abu Nuwar among the army brass and the negative effects that his anti-Western hostility was having on relations with Jordan's principal Western allies, the UK and US; Hussein viewed the latter two as much-needed alternatives of financial support to Jordan in lieu of his disappointment with the ASA.
