The Soviet Union signed the non-aggression act called the Molotov-Ribbentrop Pact in Moscow on August 23, 1939. Officially the Treaty of Non-Aggression between Germany and the Soviet Union, it effectively allowed Germany and the USSR to divide Poland between them. It did not, however, deter Hitler from attacking the USSR, anyway, in June, 1941.

World War II was a global conflict that lasted from 1939 to 1945. Key events included the invasion of Poland by Germany in 1939, the attack on Pearl Harbor by Japan in 1941, the D-Day invasion of Normandy in 1944, and the dropping of atomic bombs on Hiroshima and Nagasaki in 1945. The war ended with the unconditional surrender of Germany and Japan, leading to the establishment of the United Nations and the division of Europe into East and West.
German rearmament violated the Versailles Treaty. The Italian invasion of Ethiopia violated the charter of the League of Nations, which was a creation of the Versailles Treaty.
Germany was considered a negative influence during World War 1 due to its aggressive military actions, alliances with other powerful nations, and role in sparking the conflict through its invasion of Belgium and other countries.
The Soviet Union
The start of WWII was caused by the German invasion of Belgium, after they had signed a nonaggression pact them. France and Britain had just barely signed a treaty that would help Belgium in case of the German's attack. Russia had also signed a nonaggression pact with Germany, but that was later disregarded. The League of Nations did nothing to stop Hitler's rise to power, and his slow gobbling up of Europe. Italy eventually allied with Germany, as did Japan. The US only joined after Pearl Harbor.
After Britain and France gave away Czechoslovakia to Germany, Russia made a nonaggression pact with Germany. Then after Germany attacked Russia, Russia allied with Britain, the USA and Free France, and other Allied nations.

Germany, Japan and Italy all quit the League of Nations, though not the only ones. Germany quit because it would have limited Hitler's plans for expansion and rearmament. Japan quit because it was criticised for its invasion of Manchuria. Italy quit because it was criticised for its invasion of Abyssinia.
The first example is the Japanese invasion of Manchuria. The League of Nations disapproved but had no means to stop the invasion. Mussolini then invaded Ethiopia in 1935, and the League of Nations was unable to take action against him. Finally, in 1936, Hitler began to remilitarize Germany, and there was no reaction from the League of Nations.
The nonaggression pact of1939 was a treaty or agreement between the Soviet Union and Nazi Germany to not fight each other in WW2. The ideology of this was to delay a two front war for Germany as long as possible, unlike WW1. Hitler never intended to keep that promise though. It was just a delaying tactic, and a good one at that. Stalin never saw it coming.

Following Germany's invasion of Poland on September 1, 1939, both the United Kingdom and France declared war on Germany on September 3, 1939. This marked the official start of World War II in Europe, as these nations sought to support Poland and counter German aggression.
