Thank you for such a detailed answer.
I'd like your take on the missile defence shield, ballistic missile defence. In 2005, Canada said that it would not join the system, but we're hearing that Canada may have changed its tune.
If Canada decided to join the system, might the U.S. say it doesn't want the dead weight? Do we have the wherewithal to be a credible partner if we decided to join the ballistic missile defence system?
