But is it a betrayal if this really is the best Brexit we can get without no-deal? And is it a betrayal if the people say 'actually, having seen that we're not going to get sunlit uplands, and it's going to be terrible for quite a few years, we don't want this any more'? What if the 'will of the people' isn't Brexit any more. Let's say young people as a group prefer not to leave, and old people as a group prefer to leave, a lot of the old people will have died off, whilst a lot of young people who previously weren't able to vote now can. That implies that the 52/48 majority isn't there any more.
