 Proposing political unity with Morocco, in August 1984, Gaddafi and Moroccan monarch Hassan II signed the Oujda Treaty, forming the Arab–African Union; such a union was considered surprising due to the strong political differences and longstanding enmity that existed between the two governments.Relations remained strained, particularly due to Morocco's friendly relations with the US and Israel; in August 1986, Hassan abolished the union.In 1981, the new US President, Ronald Reagan, pursued a hard-line approach to Libya, claiming it to be a puppet regime of the Soviet Union.
