nytimes.com – The State Department spokesman, John Kirby, declined to comment on the memo, which top officials had just received. But he said Mr. Kerry respected the process as a way for employees “to express policy views candidly and privately to senior leadership.”

Robert S. Ford, a former ambassador to Syria, said, “Many people working on Syria for the State Department have long urged a tougher policy with the Assad government as a means of facilitating arrival at a negotiated political deal to set up a new Syrian government.”
