MacArthur was racist like most people, but in the end he realized the truth or at least like people to remembered him differently.
http://www.youtube.com/watch?v=Qg-PgXt8Tkc MacArthur, who had spent so much energy leading the fight against Japan, And he added that the biggest mistake which the United States had made in the 20th century was that they allowed the spread of communism.
Here are some of MacArthur quote:
“Their[Japan] purpose, therefore, in going to war was largely dictated by security.”
“The Japanese people since the war have undergone the greatest reformation recorded in modern history, With a commendable will, eagerness to learn, and marked capacity to understand, they have from the ashes left in war’s wake erected in Japan an edifice dedicated to the supremacy of individual liberty and personal dignity and in the ensuing process there has been created a truly representative government committed to the advance of political morality, freedom of economic enterprise, and social justice.
Politically, economically, and socially Japan is now abreast of many free nations of the earth and will not again fail the universal trust. That it may be counted upon to wield a profoundly beneficial influence over the course of events in Asia is attested by the magnificent manner in which the Japanese people have met the recent challenge of war, unrest and confusion surrounding them from the outside and checked communism within their own frontiers without the slightest slackening in their forward progress.
I sent all four of our occupation divisions to the Korean battlefront, without the slightest qualms as to the effect of the resulting power vacuum upon Japan. The results fully justified my faith.
I know of no nation more serene, orderly and industrious, nor in which higher hopes can be entertained for future constructive service in the advance of the human race.”
