When you use it
Use when ordering the interwar aggressive acts by Axis powers and identifying the immediate trigger of World War II.
Watch out
World War II officially began with the German invasion of Poland on September 1, 1939, not with the 1938 Munich Agreement or earlier territorial annexations.
