This Week's Embassy Magazine picks up on a surreptitious edit to the Foreign Affairs and International Trade Website (changes in bold):
Canada has long held a policy objective of non-proliferation, reduction and elimination of nuclear weapons and other weapons of mass destruction. We pursue this aim steadily, persistently and energetically, consistent with our membership in NATO and NORAD and in a manner sensitive to the broader international security context.
As the editorial notes, this change "strips Canada's policy of any real meaning. ", and I would add that it makes our nuclear policy hostage to that of our NATO allies, esp. the United States, who may be preparing to let the bunker-busters fall like rain over Iran.
