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.
I believe so... Germany invaded Belgium even though they remained neutral more info at http://militaryhistory.suite101.com/article.cfm/the_belgian_army_of_1914_
Spain was essentially Neutral in WW2. Tacit support for Nazi Germany is evidenced for example in Ewen Montgues' excellent book 'The Man Who Never Was', a deception excercise in which the British planted disinformation with regard to where the invasion would be after Tunis.
Neutral Countries that Nazi Germany invaded were Poland, Czechoslovakia, Norway, Holland, Belgium, Luxembourg, Yugoslavia, Albania, Greece, Finland, Soviet Union, and lastly the United States.

Germany's brutal invasion of neutral Belgium
Great Britain declared war on Germany.
On 19 April 1839 the Treaty of London signed by the European powers (including the Netherlands) recognized Belgium as an independent and neutral country. Despite it's neutrality, Germany invaded Belgium anyway to surprise the French army who did not expect Germany to cross neutral Belgium. Because of the German invasion Belgium became part of the "Allies" and was not neutral during the rest of the war.
Belgium was a neutral nation
In the past the Germans have invaded many countries, but the neutral country invasion that angered Americans most was the invasion of Belgium.

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.
Luxembourg was a neutral country during World War II but was invaded by Germany in May 1940. After the invasion, it was occupied by German forces and effectively became part of Nazi Germany. While Luxembourg's government-in-exile supported the Allies, the country itself was not an active participant in the war on either side.
