As the Americans discovered in the decades that followed, it is difficult to occupy a country on the other side of the world if the locals don’t want you there. Korea, Vietnam, Lebanon, Iraq, and Afghanistan were often more than the Americans could handle when they were managed one at a time. Imagine what it would have been like to occupy Germany and France and Italy and Turkey and Arabia and Iran and Pakistan and India and Indonesia and Malaysia and Japan and China (and Korea and Vietnam and Lebanon and Iraq and Afghanistan) all at once.
