"I don't know," I shrugged. "It's too early to tell." Given that the handsome liberal president had been shot dead a half-century before, my answer was a lame joke based on an apocryphal story. Henry Kissinger once said that when he asked Zhou Enlai, "What was the effect of the French Revolution on world history?" the Chinese statesmen replied, "It's too early to tell."

True to Kissingerian form, the story turns out to be not exactly true. Zhou was actually responding to a question about France's political convulsions in 1968, not 1789.
