World War I was a war between Imperialist countries, World War II was won by the Soviets (who were responsible for 90% of Nazi deaths), and the Korean “War” was an act of genocide from the United States against the Korean people, both to the north and south of the 38th parallel. The United States was in World War I as a creditor, which partially led to World War II as all of the allied powers shifted their debts to Germany, aiding in the rise of Nazism.
Military intervention does not mean harming world peace. Examples, World War I and II and Korean War.
