Yes. However in another era it was said that you can conquer the Empire from horseback, but you cannot rule it from horseback. Sadly it may turn out that Obama's ghost writer's claim that 25 million people have to die for "utopia" to arise may be the river that has to be crossed from conquest to rule.
It would be the mother of all political river crossings so I believe that 25 million number is a conservative estimate.
Additional millions will be comprised of societies dregs if the crossing is successful.
