How are we going to “take out” all these people? We don’t even know where most of them are and their alliances are constantly shifting so it’s not like we can surgically remove them.
We’d have to have blitzkrieg warfare over a vast territory killing hundreds of thousands if not millions. We would then have a vast territory we could not hold. We don’t even have enough military personnel to hold Iraq much less a much larger region.
Then there is Russia and Iran.
If we don’t fight them THERE we will have to fight them HERE and we are. There are people THERE who know who these people are and where they are and people THERE more than willing to assist in taking these savages out EVERYWHERE.
