Especially in reference to the Corbyn/Foot analogy I have long been saying "History repeats itself, it has to because no one is listening.

And that applies on grander scales - if you don't like horror stories don't read this prediction History repeats itself. That’s bad news for the 2020s - the article is upbeat only in that we can solve the impending problem "if we choose".

But as with the LP - ya can't solve problems while ya shouting at each other over how to solve the problem. The LP's problem being - how to get to be in a position of power.
