A strategic aim would require a unitary purpose that could be succinctly outlined. It would require additionally a compelling clarity about the means by which the aim would be achieved and a coherent vision about what a successful outcome would actually look like.
Winston Churchill described the aim of WW2 as the destruction of Germany. But this was ‘platitude’, and no strategy. Why was Germany to be destroyed? What interest did destroying such a major trading partner achieve? Was it to save the imperial trading system? The latter failed (after ‘Suez’) and Germany went into a deep recession. So, what was the end result intended to be? At one point, a completely de-industrialised, pastoralised Germany was postulated as the (improbable) endgame.
