Final answer:
The potential abdication over entry into WWI was influenced by European leaders' reluctance to admit the futility of the war and fear of the rise of Socialism, along with strategic considerations for the US, including the German threat and the Bolsheviks' rise in Russia.
Step-by-step explanation:
During World War I, numerous factors contributed to the potential abdication over entry into the conflict, complicating peace efforts and influencing US entry into the war. Leaders in Europe were primarily concerned that agreeing to President Wilson's notion of "peace without victory" would imply that the immense casualties suffered during the war were in vain. This was coupled with fears that ending the war without a decisive victory would fuel the rise of Socialism, challenging the existing leadership and potentially altering political dynamics.
Furthermore, strategic factors shifted the US position from neutrality. The US favored entry on the Allies' side due to concerns that Germany might succeed and the Bolsheviks might gain power in Russia, which would alter the global balance.
