Harry and Meighan can say anything, safe in the knowledge that they will never have a response from the RF. I guess there will be MM book in the next year, and hopefully this will all fade away in a couple of years. They need to be cut off so they can only repeat the past, and have no fodder for the future.
This is doing Harry no good at all...even if he makes the money he wants he's not going to be happy. The A listers they want to be friends with will continue to steer clear of this train wreck, and he's destroying his relationship (what's left of it) with his family. Charles will have a hard time convincing William to extend olive branches now.
I hope they stay away from the Coronation. Just like the Queen's death they will make some sort of fuss, and find something to be offended by. The damage to his brother that Harry is willing to do, just for revenge and money, isn't going to be forgiven. He says he wants a reconciliation - what he means is that he wants a public apology that says it's all everyone else's fault, that H&M can get everything they want, not do the dull work of being a Royal, and do everything possible to overshadow/destroy W&K for H&M benefit. I don't understand how they can expect to be part of anything going forward.
