Nuclear disarmament.

He remains a member of the ICAN Australia Committee and ICAN's International Steering Group. In 2010, he told the "Sydney Morning Herald": "We've come a long way. The numbers of nuclear weapons have been reduced from the peak of 70,000 in 1986 to about 23,000 - that's a drastic reduction."
Ruff co-authored an article with former Australian Prime Minister Malcolm Fraser entitled "2015 is the year to ban nuclear weapons." In 2017, Ruff expressed his pride at the work of ICAN and its receipt of the 2017 Nobel Peace Prize for “its work to draw attention to the catastrophic humanitarian consequences of any use of nuclear weapons and for its ground-breaking efforts to achieve a treaty-based prohibition of such weapons”.
