FYI, prior to 2009 North Korea had 5 missile tests, all of the SCUD type.  i.e. very short range.  In just over 8 years NK has developed the ability to target North America.  Actually a very weak argument, that talking has prevented NK from launching & killing millions when NK never had the capability before this year.  But NK has the capability today to kill millions and the groundwork i.e. research to develop that capability was done before Jan 20.
