Fallacy is a derailment of strategic maneuvering which is quite often appealed to by politicians in their attempts to persuade others that their points of view are right. However it seems that this field of language use has not been given its due attention despite its importance. In fact it is an area of study which is still virgin and requires a lot of investigatory work. Hence this work attempts to deal with fallacy in political speeches. Precisely it is concerned with pragmatically studying it in George W. Bush's Tony Blair's Barak Obama's and David Cameron's political war and electoral speeches.
