WASHINGTON - Targets of pervasive Chinese cyber attacks hope the latest breach of Google email will spark a robust U.S. response but Washington may find it hard to pin precise blame on China and cannot go too far against a key economic and diplomatic partner.
An aggressive stance is the only thing that forced China to budge on problems like counterfeiting or trade barriers, proponents say. Skeptics worry about adding another contentious issue to fraught ties with a major U.S. creditor and say a smoking gun is hard to put in Beijing's hand.
