Here's what passes for funny in a room packed full of weapons-industry executives and lobbyists: When Vice Adm. Joseph Rixey - the man in charge of the Pentagon agency that administers foreign arms sales - said I know you don't go after human rights violators for potential customers." The line produced chuckles in the room. Rixey was the guest of honor at a reception Wednesday hosted by the Senate Aerospace Caucus, a group of more than a dozen senators who "work to ensure a strong, secure, and competitive American aerospace sector." The event ... was cohosted by the Aerospace Industries Association (AIA), the lobbying group for weapons contractors like Lockheed Martin, Boeing, Northrop Grumman, and Raytheon. Rixey is the director of the Defense Security Cooperation Agency (DSCA), the Pentagon agency charged with overseeing the Pentagon's relations with the militaries of U.S. allies. Over the past year, the DSCA has approved upwards of $47 billion in such contracts, for weapons transfers to countries like Egypt, Israel, and Saudi Arabia. In his own remarks, Rixey lauded the relationship between the DSCA and industry. "We at DSCA are thankful that we have the support of our counterparts within the United States government and with defense industries," he said. Rixey was joined by caucus co-chairs Sens. Jerry Moran, R-Kan., and Patty Murray, D-Wash., who praised the industry for its role in overseas weapons sales on both foreign policy and economic grounds.
