"Within a short time, Ambassador Kenneth Keating, the ranking United States diplomat in New Delhi, had added his voice to those of the dissenters. It was a time, he told Washington, when a principled stand against the authors of this aggression and atrocity would also make the best pragmatic sense. Keating, a former senator from New York, used a very suggestive phrase in his cable of 29 March 1971, calling on the administration to “promptly, publicly, and prominently deplore this brutality.” It was “most important these actions be taken now,” he warned, “prior to inevitable and imminent emergence of horrible truths.”"
