Britain's attempt to distance itself from Israel as London sought to conciliate the Arab world in the aftermath of the Six-Day War has entered the historiography of Anglo-Israeli relations. A neglected aspect of the development of British policy towards Israel has been the intense debates among British decision-makers regarding the supply of tanks to Israel following the 1967 conflict. British reluctance to export the powerful Chieftain tank to Israel stemmed not only from an unwillingness to fuel an arms race in the Middle East, but also from a determination to protect ongoing and extensive British economic interests in the Arab world, especially oil supplies. In keeping with efforts to dissociate itself from Israel, Britain also sought to downplay, and even conceal from the Arab world, ongoing sales of the less sophisticated Centurion tank to Israel. In many ways, British policy towards Israel culminated in the decision during the 1973 Yom Kippur War to maintain an arms embargo to the region which, while not extending to all Arab countries, hit Israel especially hard as it desperately sought ammunition and spares for its Centurion tanks.
