chance to "solve the Jewish problem" through emigration. In particular, Hans Frank, governor of the General Government (the occupied portion of Poland), viewed the forced resettlement to Madagascar as being preferable to the heretofore piecemeal efforts at deportation into Poland. As of 10 July, deportations into Poland were cancelled, and construction of the Warsaw ghetto was halted, since it appeared to be unnecessary. Planning continues Rademacher envisioned the founding of a European bank that would ultimately liquidate all European Jewish assets to pay for the plan. This bank would then play an intermediary role between Madagascar and the rest of the world, as Jews would not be allowed to interact financially with outsiders. Göring's office of the Four Year Plan would oversee the administration of the plan's economics. Additionally, Rademacher foresaw roles for other government agencies. Ribbentrop's Foreign Affairs Ministry would negotiate terms with the French for the handover of Madagascar to Germany. It would also play a part in crafting other treaties to deal with Europe's Jews. Its Information Department, along with Joseph Goebbels and his Ministry of Public Enlightenment and Propaganda, would control the flow of information at home and abroad. Viktor Brack, a division chief in the Chancellery of the Führer, would oversee transportation. The SS would undertake the expulsion of the Jews from Europe and govern the island as a police state. The Nazis expected that after the invasion of the United Kingdom in Operation Sea Lion that they would commandeer the British merchant fleet to transport the Jews to Madagascar. The Nazis expected many deportees to perish in the harsh conditions or die at the hands of the SS. The plan has been characterised by the historian Ian Kershaw as genocide by an alternative method. Plan abandoned With the failure to defeat the Royal Air Force in the Battle of Britain, the proposed invasion of the UK was postponed indefinitely on 17 September 1940. This meant the British merchant fleet would not be at Germany's disposal for use in evacuations, and planning for the Madagascar proposal stalled. In late August 1940, Rademacher entreated Ribbentrop to hold a meeting at his ministry to begin drawing up a panel of experts to consolidate the plan. Ribbentrop never responded. Likewise, Eichmann's memorandum languished with Heydrich, who never approved it. Establishment of ghettos in Warsaw and other cities in Poland resumed in August 1940. The plan was officially shelved
