"if you could go back in time, would you kill hitler before he came to power?"
and, everybody says yes. invariably. i might introduce a caveat: i need to be given a way back to the future, or it's not worth it. i'm alive - and the past already happened.
will we ask one day if we would bomb the isis camps if we could go back in time and do it?
and, will we all agree that we should?
