The Germans were allied with the Ottoman Empire in WW1 so islam was a major factor in that conflict.If not having to fight the Ottomans in the south Russia could have devoted more to the fight against Imperial Germany;and the British troops there could have been used in Italy or France.Likely enough to have tipped the scales before the United States entered the war.
Yes,
I only referred to the plot of Wonder Woman. She is an Israeli actress and the Arab states Israeli boycott has been applied to the movie. But no mention of Islam with Germany in the movie plot. In other words, Wonder Woman is not fighting or defeating Islam in the show. So the Arabs boycott is strictly the Israel hatred manifesting itself.
