There was an excellent talk by Professor Thakur, Director of the ANU Centre for Nuclear Non-proliferation and Disarmament on the new UN treaty to outlaw nuclear weapons, Building Nuclear Peace. You can hear the whole speech in the Hawke Centre podcast of the event, or get a quick overview in this interview from 3d’s Environment Show.
Also of considerable interest is the acceptance speech last Sunday night, as ICAN was awarded this year’s Nobel Peace Prize. It starts at the 50:51 mark in the ceremony video.
