Our past policies were bad because the US promoted free enterprise, capitalism, and individualism. The world resisted such failed, radical ideology, and we became entangled in many wars as a result.
However, with Obama at the helm, the world sees that we have come around in our way of thinking, and as a nation we finally understand the benefits of a collective society ruled by a centralized socialist govt. Unfortunately, many nations have moved away from such thinking, and it is our duty to reintroduce collectivism to them, by force if necessary. We must take up the banner from our fallen comrade, the USSR! With Obama leading the charge, we can bring about the Worker's Paradise, and Marxism will finally dominate the world as it should.
