The problem is that American defense contractors don&#x27;t get a slice of this pie, while exporting arms for whatever reasons = $$$. There is also the political pressure from some such leading luminaries as John &quot;I can&#x27;t feel my feet!&quot; McCain to throw weapons at every problem.<p>I agree though, this is pretty clever. It&#x27;s not quite the RoK building a giant bank of speakers on the DPRK border, but it&#x27;s probably more effective.
