Needless to say, the Committee's efforts were thwarted.
There was a widespread belief that so-called "merchants of death" spearheaded a profit-driven effort to encourage U.S. intervention into World War I. The Committee named names and came to some forceful conclusions, most of which are just as relevant today:
The committee finds, under the head of the effect of armament, on peace, that some of the munitions companies have occasionally had opportunities to intensify the fears of people for their neighbors and have used them to their own profit.
The committee finds, further, that the very quality which in civilian life tends to lead toward progressive civilization, namely the improvements of machinery, has been used by the munitions makers to scare nations into a continued frantic expenditure for the latest improvements in devices of warfare. The constant message of the traveling salesman of the munitions companies to the rest of the world has been that they now had available for sale something new, more dangerous and more deadly than ever before and that the potential enemy was or would be buying it.
While the evidence before this committee does not show that wars have been started solely because of the activities of munitions makers and their agents, it is also true that wars rarely have one single cause, and the committee finds it to be against the peace of the world for selfishly interested organizations to be left free to goad and frighten nations into military activity.
The committee finds, further, that munitions companies engaged in bribery find themselves involved in the civil and military politics of other nations, and that this is an unwarranted form of intrusion into the affairs of other nations and undesirable representation of the character and methods of the people of the United States.
