All your base are belong to us
Obviously, we know who would stay and who would leave if the losties where given the choice by the boaties.
But assuming Ben isnt lying this time, and the boaties are bad-
Are the losties really going to have a choice?
Jack: What happen ?
Ben: Somebody set up us the bomb.
boaties: How are you gentlemen!!
boaties: All your base are belong to us.
boaties: You are on the way to destruction.
Jack: What you say!!
boaties: You have no chance to survive make your time.
IMO, It will be a while before anyone gets off the island. A new war will be starting, and we have only seen the beginning of it.
