WW2 - World War II
After Nazi-Germany in March 1939 had occupied the remains of Czechoslovakia, the British ambassador was recalled from Berlin and Neville Chamberlain declared that if Hitler attacked Poland, considered next in turn for an assault by the Third Reich, then the UK and France would give Poland "all support in their power", a promise soon also given to Greece and Romania after Italy's conquest of Albania on April 7, 1939.
A formal military alliance was concluded between the UK, France and Poland on April 6th, 1939, whereafter also the Soviet Union initiated alliance negotiations, although unsuccessfully. The Soviet Union would instead agree with Nazi-Germany in the Molotov-Ribbentrop Pact of August 1939.
