If miners can agree on not mining on top of blocks > 300kB even though that is the longer chain, they could also agree on not mining on top of a hostile 51% attack chain rolling back legitimate Bitcoin history.

Shower thought. How to socially prepare a formalisation to react upon a politically (not economically) motivated 51% attack that could roll back the blockchain not only a few blocks but days or weeks, causing disastrous consequences if the honest miners blindly switch to the longest* but evil chain. A social control is needed to prevent this.
  1. How could it look like?
  2. What do you think will happen if such an attack happened tomorrow?
Discussion is opened.
(I think it is good to think about it before it happens - just to be prepared. The worst thing one can do is to deny the possibility that it can ever happen. Conversely, if it is seriously taken into account and counter measures are prepared, then the likelihood that it happens is minimized.)
*Edit: Of course when I say "longest chain" I mean "chain with most POW". Don't correct me on this - that's semantics, you know what I mean...

As a protection against 51% attacks, Bitcoin Cash ABC will have a Trusted Central Authority that will publish a new official checkpoint, 10 blocks in the past, after every block is mined. Finally: a decentralized currency that you can trust.
