"One of the main purveyors of violence in this world has been this country"

This quote by Danny Glover is an effective statement about the function of the United States in worldwide violence. It suggests that the United States has been a major contributor to violence worldwide, either through its own actions or through its assistance of other countries' actions. This might refer to the US's participation in wars, its support of overbearing programs, or its diplomacy choices that have resulted in violence in other nations. It might also refer to the United States's function in the international arms trade, which has been connected to violence in lots of parts of the world. This quote is a tip that the US has a responsibility to use its power and influence to reduce violence worldwide, rather than contribute to it.
