Two important concepts that our chapter on Foreign policy discusses are the values that drive foreign policy and the specific instruments that are utilized to carry out foreign policy. In the post-9/11 and Afghanistan/Iraq Conflicts era, do you think that our foreign policy values have been permanently changed from those held before or just merely adapted? Also, do you think we have forever changed the instruments we rely upon to carry out foreign policy? What general trends and practices do you think we will see in US foreign policy over the next few decades?
