This paper explores the impact of Czech domestic politics on the United States' quest to gain Czech support for the radar. It begins with an overview of European Missile Defense and why the United States desires a radar in the Czech Republic. It continues with a description of the political situation in 2002 when the US first approached the Czech Republic with the idea of hosting a radar. It then proceeds to describe the on-going domestic political scene until the bilateral agreements were signed in 2008. The paper explores evidence found in the agreements to indicate the impact of Czech domestic politics and then derives conclusions from the history and evidence observed.
