Fern, in the comments asked the following question:
Litvishe--What exactly do you think needs to be done by those that participated in the disengagement to repent and earn the forgiveness of those affected (I'm not being sarcastic, I'm curious)?
I started writing a response in the comments and noticed it was going a bit long, so I decided just to make post out of it. So here is my answer:
To go each and every person uprooted from his house and hand him a check for all that he put into building his life at the very least. Not requiring the people to behave like beggers, supplicating for the money to pay the mortgages of the houses the Government kicked them out of and destroyed. Giving families not only restitution for monetary damage for property lost/destroyed, but enough that they can rebuild their lives with honor. Help them get jobs to replace those that were razed along with the communities they were based in.
Much of the more serious damage that needs to be addressed, and which I think will be harder, if not impossible, to repent for, is that done in the post-expulsion period. Where children saw their parents treated like doormats. Were left to rot in tent cities, hotel rooms where the hotel staff treated them like gargage etc. etc.
That will take years of work and investment to even begin to undo the damage. Before that, there isn't much to talk about.
Additionally, as one reader mentioned to me, it's not enough to make a blanket statement, to get up in public and klap "Al Chet" (beat one's chest and declaim one's guilt), one needs to go to the injured party and personally ask forgiveness. So, when General HaCohen goes door to door, and speaks to every man, woman and child that was brutally thrown from his house and ask for that person's forgiveness, then it is all so much lip service. He's trying to assuage his own guilt without doing anything about it.
