US now in the hands of a group of extremists - Soros

In a follow-on from another article I posted about (the Bubble of American Supremacy), George Soros, writing in the Guardian, charges that a small group of extremists has control of the US government. The crux of his charge is this:

The US can lose its dominance only as a result of its own mistakes. At present the country is in the process of committing such mistakes because it is in the hands of a group of extremists whose strong sense of mission is matched only by their false sense of certitude.
This distorted view postulates that because we are stronger than others, we must know better and we must have right on our side. That is where religious fundamentalism comes together with market fundamentalism to form the ideology of American supremacy.
