Whether or not you ascribe to the Bible, the story is an archetype that holds wisdom. Basically Nimrod aspired to create a one world government, which is what imperialist over the centuries always do. What Nimrod also sought was to build an artificial mountain to the heavens, create a portal to the "gods", bypassing the one God. Neither of the endeavors benefit mankind. So God destroyed the tower and confused the languages, He then assigned the governance of the nations to seventy of Satan's rebels, known to the humans of the time as gods, and kept one nation for himself, the Hebrews, everafter known as God' chosen people. So the question remains, what was the objection to a one world government?
All the more reason for professing Christians to demand a dissolution to the military industrial complex.
