An iron triangle refers to the stable, mutually beneficial relationship between three key players: a government agency, a congressional committee or subcommittee, and an interest group or industry. In the context of defense, the relationship between the Pentagon, Congress (specifically the Senate and House committees on defense), and defense contractors like Boeing and Lockheed Martin exemplifies this concept. This triangle influences public policies related to military spending, procurement processes, and defense contracts. The discussion also seeks examples of other companies with the capacity to engage in similar government contracts, emphasizing the need for firms with substantial size, experience, and financial resources to compete in the defense and infrastructure sectors. Further information on iron triangles can be found on various educational and governmental websites that explore political science and public policy.
