Why should Canada have any military commitments with the US? The US attacks weak countries and does not need military help. The help it gets, in general is tokenism with Britain and Australia possible exceptions. Look at the contributions of NATO countries in Afghanistan. The US is the world's bully. It is to be hoped that the US does not play with China the way it has played with the USSR. Further it is fortunate for the US that 1.6 billion Muslims are not advanced technically and wealthy.
