...no plan of operations extends with any certainty beyond the first contact with the main hostile force.
Helmuth von Moltke the Elder
Everyone has a plan ’till they get punched in the mouth.
Undefeated MMA fighter Ronda Rousey finally faced a boxer and her plan to grab and potentially break her opponent’s arm did not survive the first punch.
Now consider Corbyn’s leadership as I have said he’s not exactly stretching the Overton Window as much as disappearing into a void of his own clumsy rhetoric. Essentially he has been talking to his fellow non-idealogical left for so long the clumsiness of language and failure to engage is painful. It’s not right or left it’s just years of talking to yourself is no preparation for leadership. This is probably confounded by a lack of understanding of the need to run your messages by people who can offer the first engagement.
