XANTHE HALL – This week I read an email exchange that made me think. Actually, it worried me deeply. In one of the messages an old friend described the Nuclear Weapons Convention â€“ an idea many of us fought for since the early nineties â€“ as a â€œfairy tale.” A second mail called it a â€œdistraction.” The authors of these mails are not government representatives from nuclear weapon states or their allies, although you might be forgiven for thinking so. Both those descriptions have been used by states that want to brush aside the idea of a convention summarily, as if only for the very stupid or naÃ¯ve. No, these were colleagues. Since the strategy of pursuing a so-called Ban Treaty has been advocated by the International Campaign for the Abolition of Nuclear weapons (ICAN), at least by its International Steering Group and staff, a fierce debate has been raging between two groups. These are principally the younger and the older generation.
