My latest and the Diplomat thinks through the middle power dilemma:
Canada’s dilemma in this regard is hardly unique. The broader question involves the degree to which military procurement policies will be guided by expectations of integration into a multi-lateral military framework. Middle powers have a choice between procurement policies that maximize their unilateral security, and policies that maximize their ability to contribute to multilateral operations. For example, the United Kingdom faces a choice between preserving its nuclear deterrent (at this point a fundamentally unilateral project), and maintaining viable conventional forces capable of operating at the sharp point of NATO.
