You can take each of the practical issues of what would constitute an effective national security policy — who is in charge, how is it coordinated, what are the resources, where do you place it, what do you do with your former institutions that played a role in these things — and each one is worth pursuing and thinking through and then pulling together into a whole.
Chacun des aspects pratiques d'une politique de sécurité nationale efficace — qui doit en être responsable, comment la coordonner, quelles ressources y affecter, où la faire intervenir, comment y faire participer les institutions actuelles — mérite une étude approfondie et des efforts sérieux de coordination.
