In the 1970s, Gulf participated in the development of new oilfields in the UK North Sea and in Cabinda, although these were high-cost operations that never compensated for the loss of Gulf's interest in Kuwait. A mercenary army had to be raised to protect the oil installations in Cabinda during the Angolan civil war. The Angolan connection was another "special relationship" that attracted comment. In the late 1970s, Gulf was effectively funding a Soviet bloc regime in Africa while the US government was attempting to overthrow that regime by supporting the UNITA rebels led by Jonas Savimbi.
