This is like the 'phoney war' phase of WWII. Everybody knows it's coming so they are getting ready for it. Nazi Germany carried out the invasion of Poland on 1 September 1939. The Phoney period began with the declaration of war by the United Kingdom and France against Nazi Germany on 3 September 1939, after which little actual warfare occurred, and ended with the German invasion of France and the Low Countries on 10 May 1940.
