Hitler's foreign policy:
he wanted the Treaty of Versailles to be overturned. Hitler hated the treaty, which he saw as unfairly weakening Germany
he wanted rearmament. Germany had been forced to reduce its armed forces under the ToV. Hitler wanted Germany to be a strong military power
he wanted all German-speaking peoples to be united in a German Reich. This would mean annexing Austria and taking territory from Poland and Czechoslovakia. This was known as Grossdeutschland
he wanted to expand Germany's territory by taking land from people he saw as inferior; this is known as Lebensraum
