What if it was caused by Germany's invasion neutral Belgium A plus question?

If Germany's invasion of neutral Belgium had been the primary cause of World War I, it could have significantly altered public perception of the conflict and the alliances involved. This invasion galvanized support for the Allies, particularly in Britain, leading to a more unified front against German aggression. The violation of Belgian neutrality highlighted the aggressive tactics of Germany, potentially resulting in a stronger moral justification for the war. Ultimately, this could have shifted the dynamics of international relations and the post-war landscape in Europe.
