後來,他在英國表示:
In reaching a decision on that matter, we must first be clear about certain rules of war. Rule 1, on page I of the book of war, is: "Do not march on Moscow". Various people have tried it, Napoleon and Hitler, and it is no good. That is the first rule. I do not know whether your Lordships will know Rule 2 of war. It is: "Do not go fighting with your land armies in China". It is a vast country, with no clearly defined objectives, and an army fighting there would be engulfed by what is known as the Ming Bing(民兵), the people's insurgents.
