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.
