As the OP says, Carney has a clear, explicit policy of reducing military (and also economic) dependence on the US, for obvious reasons. It's what Carney is best known for, his leading international affairs and economic policies.
Every time a similar story, of a country turning away from US trade, is posted HN, people post that it's not political. Not only is that claim thin and largely unsbustantiated, but why is it such a focus?
