No, (s)he isn't smoking crack. While the NSA shortened the key length, they also changed DES to be resistant to differential cryptanalysis, well over a decade before differential cryptanalysis was discovered by anybody in the general public. (BTW, differential cryptanalysis is the basis of the attacks now being conducted against all these hash functions.)
