Looking at their upcoming launch manifest I see: NASA, Orbcomm, Asiasat, Space Systems, Loral, Thales Alenia Space, US Air Force, CONAE, NSPO, Spacecom, Bigelow Aerospace, SKY Perfect JSAT Corporation, SES, Iridium, and SATMEX.
The US government isn't even the customer for a majority of the launches through 2015. If you're specifically talking about manned missions you might have a better argument. But even then the Bigelow Aerospace launch is tantalizing hints of the future... even if it's only the future for the fabulously, ridiculously wealthy.
