包括时间地点人物，你所说的日本首相和LBJ密谋对中国使用核武的出处。这是一个对事实的歪曲。
"
The President said in reply to a question that Prime Minister phrased about defense that, since Japan possesses no nuclear weapons, and we do have them, if Japan needs our nuclear deterrent for its defense, the United States would stand by its commitments and provide that defense. The President asked whether that struck at the heart of the Prime Minister's question. The Prime Minister confirmed that that is what he would like to ask but said that he is unable to say so publicly. The President said that his reply on the defense of Japan is affirmative, adding that this exchange befits statesmen of the type he and the Prime Minister wish to be in the interest of their peoples.
"
当时LBJ回到日本首相关于保护日本的询问时说： 日本没有核武器，美国有，如果日本需要美国的核遏制力量来保护，美国愿意履行承诺给予提供。日本首相确认这是他想要问但不能公开问的问题。LBJ回应说他肯定了美国的义务，并补充说这个意见交换是为了人民的利益。
把这个说成日美密谋对中国使用核武，是对事实的扭曲和对历史人物的诬蔑。
