Episode notes
Why The War Lasted So Long
- Expectations shifted from a 'short-war illusion' in 1914 to a 'long-war' mindset by 1917, surprising many when 1918 ended quickly.
- Military, diplomatic, and domestic political stalemates reinforced each other and prolonged the conflict.
The Triple Stalemate Trap
- Stevenson frames WWI as a triple stalemate: military, diplomatic, and domestic political deadlock.
- Each stalemate amplified the others, trapping leaders who could not plausibly accept compromise.
The Eastern Window Of Opportunity
- Russia's exit and Brest-Litovsk freed about 40 German divisions to move west, creating a short 'window of opportunity.'
- The arrival of American forces then closed that window before Germany could secure a decisive victory.
