Bush is a tool of those who will bring about Armageddon, no doubt, but it is not their intent to bring about Armageddon. That will happen as a result of their actions to bring the wealth, resources and surviving population of the world under their control and enslavement.
According to prophecy, we still lack a false Messia sitting on the throne Jerusalem before the 200 million man army from the east attacks and begins the endgame of Armageddon. Whether that happens of not, the move to one world government is real and proceeding. If we do not wake up and stop it, nothing short of an Armageddon will.
