Answer:
Hitler kept expanding German territory across Europe.
Explanation:
Following the appeasement policy of Anglo-french policy in 1930 which gave Germany the authority to expand its territory to the German-speaking part of Czechoslovakia, the reaction of Adolf Hitler was that he kept expanding German territory across Europe.
This because after the expansion to Czechoslovakia territory, he further expanded the German territory through the invasion of Austria, Poland, and Belgium before the French and British declared war against Germany.
