Learn English – What does “left the rest behind” mean in this sentence

The Mandela quote is in a different context i feel. “It is better to lead from behind and to put others in front, especially when you celebrate victory when nice things occur. You take the front line when there is danger. Then people will appreciate your leadership.” Mandela here is definitely saying that Leading from Behind means that the leader should step back when the group or organisation or nation is celebrating something and step in to the front only when there is need for him/her to lead from the front.

So if we refer to Mandela's quote, then what Obama's statement means is quite remarkable. It would mean that the US won't get involved in the Libya issue but will be there to take credit by staying behind the scenes if things get better.

Another way to look at it would be that it was a diplomatic sort of a response to the matter at hand. Obama washed all responsibility off his hands in a manner of speaking.

As stated by yourself, Harry doesn't like anyone to be interested in the Daily Prophet.

When "Harry" said 'you and the rest of the world', he is stating : "Everyone reads the Daily Prophet!"

It's the same when someone say, teases you. You could get upset and say "No one likes me anymore!"

Not really literally no one. It's just an expression.
