WASHINGTON (AP)- President Barack Obama says North Korea's failed rocket launch shows the country is wasting money on rockets that  "don't work" while its people starve.

Obama told a television interviewer that the North Koreans have been trying to launch missiles like this for over a decade now, and they don't seem to be real good at it.

Still, he called the failed launch Friday an area of deep concern for the United States. He says in an interview with the Spanish-language TV network "Telemundo" to be broadcast Friday evening that the U.S. will work with other nations to ``further isolate'' North Korea.
