    A warm welcome -

    Marilyn Monroe entertains the troops in Korea in 1954. The actress would say more than once in her life that the adulation she felt in Korea by the servicemen -- a group of fans who had helped make her a star -- was the high point of her career. As she performed before thousands of troops in bitter cold temperatures, wearing only a scanty, plum-colored dress, she acknowledged her debt to them as they warmed her with their unconditional adoration.
