I think that Changez discussing the issue of "nostalgia" helps the reader understand the current political situation post- September 11. Changez's appropriation of the concept of nostalgia helps to bring forth the nationalism and zealous defense of country that happens after the events of September 11. Changez's discussion of nostalgia is one in which America is both inwardly drawn and outwardly desirous of appropriating the world in accordance to its own subjectivity. Changez makes it clear that the political situation that followed September 11 is one in which America sought to construct itself in the mode of a World War II nation that believed in its own certainty to be able to move freely all over the world without any regard or outward opposition. For Changez, the construction of nostalgia helps to explain this element of America's foreign policy. At the same time, it brings forth the fear and lack of reflection that dominated the political situation of the time period. In discussing America's nostalgia, Changez is able to explain to the reader how the political discourse and situation in America following September 11 was one in which there was a definite "us versus them" mentality and people like Changez were marginalized as the "them" component.
