How Should a Nation-State Develop its Foreign Policy in Accordance to its Values and in Connection to the Development of its Domestic Policy?

Wow!  What a question!  For me I had to first say, "OK, what is a nation-state, what is a foreign policy and what is a domestic policy"?  A nation-state is just a country, USA, Canada, England, etc., a foreign policy is how you engage with other nation-states and a domestic policy is how you engage in your own nation-state.  With that being said, it is clear to me that a foreign policy and domestic policy are very interconnected.  They both effect the other a great deal.  When engaging in a foreign policy, the values, goals, benefits, must be in accordance with the values, etc. as yours.  A nation-state would want to know, is this good for us economically, politically, military wise; how is this going to effect us.  "Ever since the establishment of the United States in the 18th century, American political leaders have consciously crafted domestic and foreign policies to achieve and maintain a favorable position in the global political economy.  In other words, American economic, military, and political dominance has not just happened; it has been made to happen" (Katznelson, Kesselman, Draper, 241).  Foreign policy and domestic policy is not set in concrete, they can change the policy if a circumstance arises and "after World War II, the United States adopted a far more activist foreign policy, a response to the decline of the major European powers, the challenge to the United States posed by the Soviet Union-a political and ideological rival-and the fear of American officials that global instability might produce a resumption of the destructive 1930s economic depression" (Katznelson, Kesselman, Draper, 243).  As America became a more powerful nation, and we started to expand, we had to take into consideration more about how our policies and how we and others would be affected.  According to the authors of The Politics of Power, "American expansion abroad has taken two major forms: economic penetration by multinational corporations into Europe and the developing world, and political and military influence exercised by the American government.  The two are distinct, yet intertwined, and each has contributed to advancing the other" (Katznelson, Kesselman, Draper, 246).  This again is just a reference to how intertwined they are.
In all, foreign policy and domestic policy are very interconnected and a nation-states values depend heavily on one another.
