-If Germans win war, the world would be a much better place than what it is now
-Related to above, the idea that a defeated France cannot radicalize in either far left or far right or neo-monarchist direction because of "democratic tradition" or "lack of resources alone standing up to Germany". You do know that they can build a containment alliance, right(and even if they don't go fascist, neo-bourbon, neo-bonaparte, or Communist we shouldn't deny the possibility of democratic leaning war hawks).
-If Germans win war, Reds would be crushed in Russia
-Likewise, if the Entente win war, Communism in Russia is inevitable no matter what
-Alternatively if Germans win war, there would be a cold war with America
-A Russia first strategy would be a instant win for the Germans
-The fall of AH or the Ottomans being inevitable no matter what
-Alternatively with the Ottomans, only a CP victory offers a slim hope for them to not collapse.
-If Germans win war, Belgium would get annexed or made a puppet state.
