Timmon Milne Wallis holds a PhD in Peace Studies from Bradford University.  He has served as executive director of Nonviolent Peaceforce, and he has directed peace projects in Colombia, Guatemala, Mexico, Northern Ireland, Kosovo, Georgia, Myanmar, Chechnya, Croatia, Sri Lanka, Philippines, and South Sudan.

He has also served as editor of Peace News, as director of the National Peace Council (UK), as international secretary of Peace Brigades International, as training manager for International Alert, and as programme manager for Quakers in Britain.  He was the founder and director of Peaceworkers UK.

His new book, Disarming the Nuclear Argument: The Truth About Nuclear Weapons, analyzes the cost, accident risk, and legality of nuclear weapons, and the absurdity of the whole concept of perpetuating nuclear weapons as “deterrence.”  The book played a role in the successful July 2017 United Nations negotiations for a Nuclear Ban Treaty, and it is a handbook for those seeking a safer, saner world.
