US grand strategy after the Cold War: Can realism explain it? Should realism guide it?

Need an outline for the topic provided. Instructions for the paper are as followed.
Conduct a review of literature relevant to an analysis of the issue/event of your choice. The purpose of the literature review is to familiarize yourself with theories/propositions, concepts, variables, methods, data/statistics that may be conducive to an analysis of your subject. c. Develop a proposition (or identify underlying themes) from the literature review and generate a ‘hypothesis.’ The hypothesis is a relational or a correlational statement between the two variables of your choice. For Example:
(1) Economic globalization and quality of life: “The more the economic globalization, the higher the level of the quality of life.” (2) Amount of trade and economic development: “The larger the amount of trade, the more economically developed.”
The hypothesis generated is what you need to (empirically) verify based on ‘several’ cases (e.g., countries, MNCs, IGOs, etc) observed in your paper.
