'When U.S. firms dominate a $70 billion a year global market, you’d expect to hear about it. Not so with the global arms trade. There are occasional pieces that, for example, take note of the impact of U.S. weapons transfers, including cluster bombs, to Saudi Arabia, or of the disastrous dispensation of weaponry to U.S. allies in Syria, or of foreign sales of the costly, controversial F-35 combat aircraft. And once in a while, if a foreign leader meets with the president, U.S. arms sales to his or her country might generate an article or two. But the sheer size of the American arms trade, the politics that drive it, the companies that profit from it, and its devastating global impacts are rarely discussed, much less analyzed in any depth.'
