Re: Why did the League of Shadows want to destroy a peaceful city?
Christopher Nolan said it was important for the League of Shadows to return, so yes, they are the League of Shadows. The League were shown in the flashbacks in TDKR to be a bunch of gunmen. The gunmen in Batman Begins at the monastery wore the same red scarves that the League members wore in The Dark Knight Rises. Bruce Wayne was never supposed to be Ra's successor, he was supposed to be Ra's' right-hand man out in front in the attack on Gotham. That's what the movie says.
