Historically, the use of armed force constitutes a source of division within Canadian society in which several conceptions oppose one another. Among them, the militarist conception of the “warrior nation” and its robust diplomacy have gained in strength since the coming to power of the Conservatives in 2006. At the heart of the conservative strategy to replace Canada’s internationalist (Liberal) identity with the foundation of a “natural governing party”, this militarist discourse breaks with the generally cautious approach of preceding governments over the last half-century. This being so, this change, far from contributing to rally Canadian society, reveals and exacerbates the tensions within the country, with the result that national unity becomes a collateral victim of the first order.
