Quotations
Negotiating with Stalin was like dealing with an octopus. At Yalta it had been agreed that Dairen in China would be an open port that the Chinese could use. And now they were trying- it'd be under the control of the Chinese, that the Russians could use is what I intended to say. And, it was now an approach, by Stalin, that would have given him complete possession of that part of Manchuria. And that, I wasn't in favor of doing.[...]Dairen would be administered by the Chinese, as a Chinese port, but it would be a free port that everybody could use including the Russians.
