Pope Francis on Thursday gently scolded Congress on a variety of issues. Speaking about his determination to minimize and, in the long term, to end the many armed conflicts throughout our world," when he said this: "Here we have to ask ourselves: Why are deadly weapons being sold to those who plan to inflict untold suffering on individuals and society? Sadly, the answer, as we all know, is simply for money: money that is drenched in blood, often innocent blood. In the face of this shameful and culpable silence, it is our duty to confront the problem and to stop the arms trade." The U.S. is by far the largest arms supplier in the world. During the Obama administration, weapons sales have surged to record levels, in large part due to huge shipments to Gulf States, particularly Saudi Arabia. A healthy chunk of those arms sales are heavily subsidized by the U.S. taxpayer. Congress, which could have blocked any of this, went along happily - in no small part because of the approximately $150 million a year the defense industry spends on lobbying and direct campaign contributions. U.S. firms make up seven of the top 10 arms-exporting companies, with Lockheed Martin and Boeing coming in at numbers one and two. In August, Secretary of State John Kerry announced that he would even further speed up U.S. arms sales to Gulf countries.
