Japan invaded America as a preventive action to prevent the interference of the United States Pacific Fleet with their planned military actions in Southeast Asia. Their strategic goals included destroying the U.S. Pacific fleet, capturing oil fields in the Dutch East Indies, and expanding their empire’s reach to create a defensive perimeter.
This invasion was also aimed at maintaining their sphere of influence in East Asia and countering the control of overseas territories by the United Kingdom, the Netherlands, and the United States.
Motive Behind Japan’s Attack On Pearl Harbor
The motive behind Japan’s attack on Pearl Harbor was driven by several factors. Firstly, Japan saw the U.S. Pacific Fleet as a hindrance to its expansion plans in Southeast Asia. They believed that once the fleet was neutralized, they would have a clear path to conquer the region.
In addition to this, economic sanctions and trade embargoes imposed by the United States were seen by Japan as triggers for their aggressive actions. Japanese leaders hoped that attacking Pearl Harbor would force the U.S. to lift these sanctions and embargoes, allowing them to continue their planned military actions in Southeast Asia.
The Japanese also had a strong belief in the conquest of Southeast Asia. They aimed to capture oil fields in the Dutch East Indies and expand their empire’s territory to create a defensive perimeter around their newly acquired lands.
Overall, these factors combined to provoke Japan’s decision to invade America and launch the attack on Pearl Harbor.
