If one reads the whole thing below and accepts it as "true" then containment is the only option, not invasion.
I'm not really following it but wasn't the Paris attacks carried out by Europeans, not Syrians, Iraqi's, and so on.
Does invading 'Dabiq' make more or less of these Europeans? More or less recruitment? More or less legitimacy for ISIS?
