In Palestine, however, conflict between Palestinian Arabs and Jews intensified. British attempts at maintaining order proved insufficient as Jewish and Arab “self-help” groups battled in the streets. Britain, to no avail, published the Passfield White Paper in 1930, an attempt to clarify the Balfour Declaration by distinguishing between ajewish “national home” and a full-fledged “sovereign state.” With the anti-British and anti-Zionist Palestinian Arab Revolt in 1936-39, Britain became fearful that the Arabs would revolt on the side of Nazi Germany if war broke out. Thus, in the White Paper of 1939, Britain severely curtailed Jewish immigration to Palestine as Jewish refugees fled the impending Holocaust. As Hitler’s genocide began, Zionists were desperate to establish their own state as a safe haven. Palestinian Arabs, on the other hand, saw the influx as an extension of colonialism and an attempt to solve a “European” problem at their expense.
