Step-by-step explanation:
With the French defeated, Hitler was now able to turn his attention across the English Channel, attempting to invade Britain. However, Hitler faced significant challenges in taking Britain after conquering France. One major obstacle was the Royal Air Force (RAF), which fought valiantly in the Battle of Britain and ultimately defeated the German Luftwaffe.
Additionally, Britain's development of radar technology played a crucial role in detecting and intercepting German aircraft. The heroic efforts of British pilots, along with Churchill's leadership, made it difficult for Hitler to gain military dominance in the skies over Britain and forced him to abandon his plans for invasion. So therefore Hitler faced challenges in taking Britain after conquering France, including the resistance of the Royal Air Force (RAF) and Britain's development of radar technology.
