What was the road to war like in Europe during the 3 years that separated the period from the Japanese invasion of Manchuria to the start of the Second Sino Japanese war?

In 1931, Japan invaded Manchuria, which marked the beginning of a chain of events that would eventually lead to the Second Sino Japanese war in 1937, which in turn escalated into the Second World War in 1939. However, while war eventually did break out in Europe in 1939, the continent enjoyed a period of relative peace between 1931 and 1937, while the Japanese invasion of Manchuria marked the beginning of a period of escalating Japanese aggression towards China that eventually culminated into a full scale war in 1937. How did people in Europe react to the changing world situation during these 6 years?
