WITH HIS HANDS FULL FIGHTING BRITAIN, AND WITH SOVIET FORCES MASSING NEAR GERMAN BORDERS, WHY DID HITLER INVADE GREECE & YUGOSLAVIA?
By Mike King

Germany controls Northern Europe, but is still vulnerable from the South and East.
Some Background Information:
In the Spring of 1940, the British had been chased out of Europe at Dunkirk (allowed to escape by Hitler) and France soon signed an armistice with Germany. For wartime defensive purposes, Germany continues to occupy Northern France, Holland and Belgium. Bases have also been established in Norway and Denmark (in response to British maneuvers aimed at establishing bases in those nations).
