A government by the people, for the people, to serve the people is the foundation that the United States prides itself on: Yet the US government, especially the Bush and now the Obama administration, have executed policies contrary to that, and against their own people.
In this edition of the show, we will look at why the US government has pursued this path, such as deciding to arm the insurgents in Syria, when clearly money generated from taxes from their own people, is being paid for these wars, against the American wishes.
We will also ask "how much control and influence do American people have on their governments and the decisions they make?
