Explanation:

The true answer here depends on every persons own opinion. Maybe to a French man, the invasion of his homeland would be the most terrifying thing - maybe to an US citizen the attack on Pearl Harbor would be terrible. But the most horrific act of WW2, globally recognized is the German army killing more than 6 million jews just because they believed in the ideology of being "the master race".
