NYTimes has booklet-length front page story on intelligence failures with respect to North Korean "speed"

The Sunday New York Times has an alarming front page booklet-length story by David R. Sanger and William J. Broad: “U.S. Miscalculated the Nuclear Progress of North Korea by Years”, with subheadline.”Flawed Estimates Rank as One of the Biggest Intelligence Failures”, link here, 

But Mike Pompeo of the CIA criticized this assessment on CBS’s “Face the Nation” today. 

I tend to agree with the NYT.  It seems that Kim had a lot of black market help from other post-Communist nations.
