How were the international relations during the inter war period?

Good to start with then really bad ending in World War Two. The League of Nations was formed which could have heralded world peace had America been a part. People were enthusiastic about peace and stability in the 20's this was known as the 'Locarno Honeymoon' when many treaties were signed that although meant little contributed to the atmosphere of hope. However economic recovery from WW1 was slow and the treaties that were signed meant little when Japan and Italy started to get aggressive the League of Nations made no effective response. The Great Depression tipped global relations down the pan and with the aid of a few other factors Hitler came to power.
