Well, I don't know about the nuclear weapons, Peter. Seems we have enough trouble keeping the nuclear power plants up and running safely!
I found hope in the fact that a thousand Canadians braved the freezing rain in a Toronto rally yesterday to show support for the US - not for the current war, but for the States as a friend, neighbour and trade partner. Story here. I think that the rally expresses the attitudes of most Canadians - anti-war, but in general, pro-US.
Bodes well for the peace and security of North America, imo!
