Game of Thrones season 8: Will White Walkers win because of SPOILER?

Months before the release of Season 7 of Game of Thrones, one wonders if the war is not already lost.
Spoilers continue to fall and then we wondered if there is little we would see another dragon north of the Wall in season 7 of Game of Thrones is now some speculation that you propose. Indeed a user on Reddit raised an interesting point about the rest of the series and could be crucial to the plot. It was discovered in Season 6 when the Night King touched Bran Stark and left him a brand, he was then able to enter the den of Corneille Three Eyes to attack them . This sad turnaround led to the death of Cornelius, Hodor and Summer Wolf. The strange magic of the White Walkers has allowed them, through this contact, to be able to enter places that are normally prohibited to them. Subsequently, Bran and Meera are saved by Benjen Stark who brings them to the Wall so that they can cross the other side. Only now that Bran has the mark on him, will not it break the magic that protects the Wall and allow the Night King and his army of White Walkers to pass on the other side?
This is not completely impossible and some Internet users go even further in the theories. According to the most inventive fans, the Night King would have purposely not kill Bran Stark and would have kept him specially alive so that he crosses the wall, breaks the spell and opens the door to the White Walkers. And if we go a little further, one might even think that for this, the Night King used a double agent who is actually on his side: Benjen Stark . Doubt has been hovering for some time on the totally human nature of Benjen and some think that he is actually a Night King pawn that used him to quickly bring Bran and Meera to the Wall. This theory is rather disturbing since it would involve not only a traitor in the ranks but an imminent threat from the north. Indeed the Wall is supposed to be protected by magic in addition to the Night Guard but we know how much the latter needs men to be really effective. Will Jon Snow, Daenerys and the others lose a war that has not yet started because of Bran? We will see very soon … While waiting to find out, it was just asked what would happen to the main characters after the war against the White Walkers in Season 8 of Game of Thrones . What do you think ?
