Abstract
In the article is the problem of discourse effectiveness is considered, in particular of political discourse of a conflict situation. Conflict political discourse is regarded as a text determined by the theme of stating the interests of political subjects in the process of their interaction in a situation of political conflict. Goal-settings of conflict political discourse expressed in its subject type of content are connected with information, persuasion, invocation, and penance that served as the basis for distinguishing the genres of political discourse. In the article, the possibility of describing discourse effectiveness according to the theory of factors of speech regulation by M. Y. Blokh is proved. Effective and ineffective political rhetoric is illustrated by two political speeches by G. W. Bush. The criterion of effectiveness was resolution-non-resolution of the conflict in a certain historical situation. In the process of research it was found out that the key role in building discourse effectiveness is played by presupposition and postsupposition factors connected with the views of the speaker and the listener on each other. Successful realization of discourse functions is also prompted by the goal content of the utterance, personal status of the speaker and the listener, level of discourse formality, and the degree of discourse impressiveness.
