Obama to Keep One Leader for NSA, Cyberwarfare

President Obama has decided to keep the National Security Agency and the Pentagon’s cyberwarfare branch under the same command despite concerns that it concentrates too much power in the hands of a single military official responsible for both surveillance and directing a growing arsenal of cyberweapons. As a practical matter, the decision means that Mr. Obama must appoint a four-star military officer to succeed Gen. Keith B. Alexander, the first person to simultaneously run the two organizations, when he retires early next year.
