and they concluded that Czechoslovakia was a principal obstacle to a "rearrangement" of Central Europe and therefore should be subverted internally, isolated internationally, and finally eliminated by military force. During a meeting with Hitler in August 1936, Miklós Horthy advocated a common attack against Czechoslovakia to excise a "cancerous tumor from the heart of Europe". In late 1937 Hitler decided to open a campaign against Czechoslovakia. In 1938 Germany and Hungary focused on creating a common platform to that end, and in November 1938 Hitler negotiated with the Hungarian government concerning the fate of Czechoslovakia. Hungarian representatives considered an overt attack on Czechoslovakia too dangerous and wanted to preserve that country's relations with France and Britain, whose support in the question of Hungarian minorities was conditional on Hungary's not joining with Germany in military actions. This outraged Hitler and led to a change in Germany's view of Hungarian territorial demands in eastern Czechoslovakia. Before the Munich Agreement, a Hungarian government emissary had officially asked the German and Italian delegations to resolve Hungarian demands together with the questions of Sudeten Germans. However, Hitler did not agree because he was not satisfied with the previous passivity of Hungary and because he had his own plans for Central Europe. The French and British delegates, Prime Minister Édouard Daladier and Neville Chamberlain, saw potential danger in such a complex solution, but the Italian delegate, Prime Minister Benito Mussolini, allowed Hungarian demands to be reflected in an appendix to the agreement. It requested Czechoslovakia to resolve the minority question with Hungary and Poland within three months by bilateral negotiations, or matters would be resolved by the four signatories of the agreement. After the annexation of Zaolzie and Český Těšín by Poland, the Hungarian question had remained open. Poland later annexed further territories in northern Slovakia (on December 1, 1938, villages in Kysuce, Orava and Spiš) comprising 226 km2, with 4,280 inhabitants (see separate article, Polish–Czechoslovak border conflicts). The Hungarian government understood the appendix of the Munich Agreement as an agreement of the Great Powers for the revision of peace treaties and emphasised that it did not mean only the revision of borders based on ethnicity but also the eventual restoration of Hungarian territory before 1918 and the creation of a common border with Poland. Official Hungarian circles were aware that Hungary alone was too weak to enforce its territorial demands towards Czechoslovakia because they knew
