Mark Norman believes an attack from the U.S. in not hypothetical. It’s already happening. And Canada’s lacking a strategy to respond.    He first laid out his argument in an opinion piece for the National Post titled  “Canada’s relationship with the U.S. can’t be saved.”   He joins Paul to explain why he thinks we need to change our national mindset towards the U.S.    Mark Norman is the former Commander of the Royal Canadian Navy and Vice Chief of the Defense Staff of Canada.   Season 3 of The Paul Wells Show is sponsored by McGill University’s Max Bell School of Public Policy.
