Us Decides to Retaliate Against China’s Hacking

The Obama Administration has determined that it must retaliate against China for the theft of the personal information of more than 20 million Americans from the databases of the Office of Personnel Management, but it is still struggling to decide what it can do without prompting an escalating cyberconflict.

The decision came after the administration concluded that the hacking attack was so vast in scope and ambition that the usual practices for dealing with traditional espionage cases did not apply. But in a series of classified meetings, officials have struggled to choose among options that range from largely symbolic responses — for example, diplomatic protests or the ouster of known Chinese agents in the United States — to more significant actions that some officials fear could lead to an escalation of the hacking conflict between the two countries.
