Vierjahresplan
Historians such as Richard Overy have argued that the importance of the memo, which was written personally by Hitler, can be gauged by the fact that Hitler, who had something of a phobia about writing, hardly ever wrote anything down, which indicates that Hitler had something especially important to say. The "Four-Year Plan Memorandum" predicated an imminent all-out, apocalyptic struggle between "Judeo-Bolshevism" and German National Socialism, which necessitated a total effort at rearmament regardless of the economic costs. The basic premise of the Four Year Plan memo was that "the showdown with Russia is inevitable".
