The meaning of “it means saying that might is right.” (The last sentence of Paragraph 2) is that _______.

参考解析：

推理判断题。根据第二段第四句“Fighting means killing, and civilized peoples ought to be able to find some way of settling their disputes other than by seeing which side can kill off the greater number of the other side, and then saying that side which has killed most has won. And it not only has won, but, because it has won, has been in the right.”可知战斗就意味着杀戮，文明的人通常会找到其他的解决争端的方法而不是杀死对方。而战争的意思却不一样，在战争角度来说，胜者为王，败者为寇。所以For that is what going to war means; it means saying that might is right.的意思就是D项内容，故选D。
