Second, this discursive construction plays a crucial role in America’s interaction with boththe American public and the rest of the world. Firstly, by overstating and pre-supposing thedanger and range of threats it encounters, the U.S. means to derive support from bothpoliticians and the public on the one hand, and make its aggressive strategies legitimate on theother hand. Secondly, by repeatedly highlighting the necessity of promoting military andeconomic strength, which is also a kind of saber-rattling, the U.S. aims to deter adversaries andpotential threats and thus enhance the sense of security. Thirdly, by boasting Americandemocratic values and making contrast with countries that oppress their people, the U.S.intends to emphasize its determination and confidence in upholding the role of a global leader.
