I don't know, Ron. I figure there are any number of identifiable groups out there who are very powerful players, but which one is the most powerful at the moment, I couldn't say. I just don't move in the right circles to be sure about that. ;-)

Going back to medieval times...you could have had a similar discussion about the royal houses of Europe, the Vatican, the Holy Roman Empire, the Knights Templar, the Inquisition, and a bunch of other powerful groups of that time. Which one was "all-powerful"? Well, I guess some of them thought of themselves that way...and there may well be someone who thinks of themselves that way now too.

The USA acts as if it is all-powerful in the world.
