Plan 2 has the Japanese invading the West Coast of America via Pearl Harbor and then California.

           

Plan 3 has the Japanese invading North America through the Panama Canal, then proceeding up through Mexico to the West Coast of the United States.

Plan 4 has the combined naval strength of the Axis powers taking over the Atlantic, leading to an eventual invasion of the United States through the Mississippi River.

Plan 5 has the Axis powers invading the United States through Norfolk, Virginia.

Plan 6 involves the Nazi’s invading the United States through Canada via the St. Lawrence and Hudson valley’s.
