And why couldn't Jack have said, "Send Kate and Sawyer back. When they call me on a walkie-talkie and tell me they are at camp, and can prove it by having Locke talk or something, then I will do the operation. That's not hard, is it?

Because this is JACK and he has to make everything harder than it is.
