Actually Gorbechev did.
Here’s an exerpt from MSNBC Story where Gorbechev sets the record straight.
‘We all lost’
But if he had warm, appreciative words for Reagan, Gorbachev brusquely dismissed the suggestion that Reagan had intimidated either him or the Soviet Union, or forced them to make concessions. Was it accurate to say that Reagan won the Cold War? “That’s not serious,” Gorbachev said, using the same words several times. “I think we all lost the Cold War, particularly the Soviet Union. We each lost $10 trillion,” he said, referring to the money Russians and Americans spent on an arms race that lasted more than four decades. “We only won when the Cold War ended.”
By Gorbachev’s account, it was his early successes on the world stage that convinced the Americans that they had to deal with him and to match his fervor for arms control and other agreements that could reduce East-West tensions. “We had an intelligence report from Washington in 1987,” he said, “reporting on a meeting of the National Security Council.” Senior U.S. officials had concluded that Gorbachev’s “growing credibility and prestige did not serve the interests of the United States” and had to be countered. A desire in Washington not to let him make too good an impression on the world did more to promote subsequent Soviet-American agreements than any American intimidation, he said. “They wanted to look good in terms of making peace and achieving arms control,” he said of the Reagan administration.
The changes he wrought in the Soviet Union, from ending much of the official censorship to sweeping political and economic reforms, were undertaken not because of any foreign pressure or concern, Gorbachev said, but because Russia was dying under the weight of the Stalinist system. “The country was being stifled by the lack of freedom,” he said. “We were increasingly behind the West, which . . . was achieving a new technological era, a new kind of productivity. . . . And I was ashamed for my country — perhaps the country with the richest resources on Earth, and we couldn’t provide toothpaste for our people.”
