International sport thrives on the very politics Olympic publicists decry. Sport organs are structured to maximize political rivalry over the Games or other major sporting events; they are neither more or less "political" than anything else. International sport is a form of cross-cultural activity which attracts the interest of, and is understood by, a mass public. States may try to use sport to represent international goodwill, but the mechanism of sport makes it a potential forum for interstate confrontation as well. The use of sport to convey a diplomatic message or to promote the identification of the citizen with the state and its policies is a regularized and systematic phenomenon. The international sport system is divided on the question of credentials for participation. States permit Olympic institutions to retain control over sport, and tend to base domestic sport programs on some version of the Olympic ideal amended to correspond to stated national goals.
