Not a relative to George.
Allow me a botanical analogy. There are many trees and plants that establish taproots. Once that taproot is established, they will send out runners, often subterranean, that will sprout at distances from the taproot. Those sprouts can often emerge through asphalt and even concrete earth coverings.
Hence the question, Is al Qaeda a 'taproot' or a a 'sprout'? A rhetorical question, for in no way is al Queda a 'taproot'. And destroying a' sprout' will not prevent the source, the taproot, from generating additional 'runners' and sprouts.
I note that George Friedman carefully avoids mentioning any of the 'runners' developing in the USA, or in Western Europe.
