I disagree, as you might expect me to, Paul.
The tension is that of a wire suspended over a chasm, anchored at each end to a tall building. One represents the current status within the EU. The other is as yet an unknown and unknowable destination.
Corbyn’s skill has been to move along the line of tension without falling in to the chasm below. His endeavour is to make the crossing without losing his balance, swayed by the calls of those who want to distract him to left or right.
His role as leader is not to decide for others, but to facilitate a new decision about the eventual nature of the destination, one that is seen as a wise and just one, and ‘satisficing’, “good enough” represent a sound foundation for all our future.
As he says often, his is only one opinion on the remain/leave polarity. He will not impose it arbitrarily on the Party nor the nation.
He is a wise leader in the tradition, perhaps, of Solomon before him: “give full attention to the outcome of your decision, now that you have conferred about it in the full light of knowledge of what it may yield”.
Those who characterise him as a ditherer are IMO like impetuous children. Bojo plays on their immature impulses and impatience to be relieved of having to watch, and wait for the full picture to emerge. “Get it done” is a primitive, premature, and perilous slogan, designed to raise tension and dismiss reason.
The “deal” he has negotiated may never ever be examined: should we should trust him with our futures, full of milk and honey and the smell of chestnuts roasting on the open fire? A unscrupulous manufacturer of worthless and unfulfilled promises?
I won’t, and I wager the British people won’t either. They have more sense.
