What is Implausible in “Man in the High Castle”

There is a lot implausible for “Man in the High Castle.” The biggest problem is that Germany and Japan could defeat the United States, especially Japan. The reason they could not be able to defeat the United States is the same reason why Germany could not defeat the Soviet Union and Britain, fuel. Both Germany and Japan were struggling with oil, especially Japan as they did not have natural access to oil. While Japan was struggling with oil, the United States had Texas, which was filled with oil. Germany was also struggling with oil, as they had to fuel their navy, air force, and army, especially their tanks. The German attack on the Soviet Union had even stalled due to their lack of fuel and other supplies. Due to this, the whole premise of Man in the High Castle is impluasible.
