If Israel did not acknowledge their avocations to return to their pre-1967 territorial state

With the oil embargo in place, the industrial governments of the world in some way altered their foreign policy regarding the Arab-Israeli conflict and after the use of the Arab oil weapon. These included European countries such as the UK who decided to refuse to allow the United States to use British bases in the UK and in Cyprus to airlift resupplies to Israel along with the rest of the members of the European Community. It also included the Japanese restatement on November 22, to “reconsider” their relations with Israel if Israel did not acknowledge their avocations to return to their pre-1967 territorial state, although this was never acted upon. Canada shifted towards a more pro-Arab position after displeasure was expressed by many Arab governments towards Canada’s Middle Eastern position as one of being mostly neutral. “On the other hand, after the embargo the Canadian government moved quickly indeed toward the Arab position, despite its low dependence on Middle Eastern oil”
