American public opinion turned against Germany in WW One & WW Two for various reasons.
In WW1, Germany invaded France & Belgium in August 1914. Because, Belgium was a neutral country, Americans were upset with Germany. The invasion of Belgium however was not the most important factor. Later, German unrestricted submarine warfare also turned American public opinion against Germany. Then as a final straw, the German's Zimmermann telegram message to Mexico further angered Americans.
In WW2, Germany invaded Poland, neutral Denmark, neutral Norway, neutral Holland, neutral Belgium, and so forth on & on. German submarine warfare also turned public opinion against Germany.
Belgium declared that its neutrality was broken during World War I when Germany violated its borders by invading the country on August 4, 1914. Belgium had been a neutral state since the Treaty of London in 1839, which guaranteed its sovereignty. The invasion prompted Belgium to seek assistance from the Allied Powers, leading to its involvement in the war against Germany. This act of aggression was significant as it also galvanized international opinion against Germany.
At the beginning of World War I, Belgium played a crucial role by allowing Germany to invade through its territory, which was part of the Schlieffen Plan aimed at quickly defeating France before turning to Russia. Despite being neutral, Belgium's refusal to grant Germany unrestricted access led to a German invasion on August 4, 1914, which in turn prompted Britain to declare war on Germany. This invasion ultimately helped France and Russia, as it delayed German forces and allowed the Allied powers to mobilize more effectively against Germany. Thus, Belgium's resistance became a symbol of Allied unity and determination.
