Arms manufacturers like Lockheed Martin, Boeing, Northrop Gruman, General Motors and Raytheon are the largest, most powerful interest groups in the U.S., claims Andrew Feinstein (The Shadow World: Inside the Global Arms Trade). The arms industry is driving foreign and domestic policies and is involved in shady and illegal business deals at home and abroad. The American arms industry lobbied for the war in Iraq. Halliburton, which gave over $1 million to the Republican Party between 1998 and 2003, was a huge beneficiary of that war. Lockheed Martin pushed for the expansion of NATO, because it called for Eastern European countries to upgrade their militaries, often buying from U.S. companies. Congressional members with defense contractors in their districts find it nearly impossible to oppose America’s going to war (review in TLS, March 30).
