Basically what this theory is saying is that Jacob is in reality, Clairs son Aaron (Turniphead). As seen in the Season 5 finale, what appeared to be a ressurected Locke, was not in fact Locke. If the smoke monster took the form of Alex and told Ben to follow the orders of John Locke, then the smoke monster itself may be John Locke we see now.
Now who else have we seen "ressurected" on this island? Christian Sheppard. And it seemed in the last season finale that he had some interest in Claire, and then took her off somewhere and we have not seen her since.
I believe that whoever it is that is the person we've seen who wants to kill Jacob, is also the smoke monster. Heard by both Charles Widmore (who like the smoke monster, wants to keep the island a secret), and Illana (who is on the side of Jacob, who wants the island to be inhabited by people and be a good place and a happy place), have stated that a war is coming. I believe that Claire will be used as a way to try and get Aaron(Jacob) to do something, somewhere along the timeline.
How Aaron becomes how he is as Jacob I do not know, but i feel it is a possible situation.
