Nuclear weaponry is offensive in nature, and Canada does not need them. The population broadly does not want them. Most people may acknowledge (after slight thought) that if we were to obtain/produce them, certainly other countries won't be happy and if we were to 'use' them, well I'm sure the fallout will end up on our own soil after it's swatted out of the sky. So, let's build AA defence/defense networks of our own, instead.
