Bush and Clinton removed the Idealism from the strategy for foreign policy. ;
I believe the answer is: idealism
In foreign policy, idealism refers to the advocation of foreign policy based on one permanent ideal or point of view.
During both bush and Clinton era, America made several foreign policy that often based on different principles, depending on whether the action would benefited united states or not.
The foreign policy strategy least likely employed by all three presidents (Bush, Clinton, and Bush) is realpolitik. While all three utilized multiple approaches, realpolitik did not define the doctrines of Clinton and the two Bushes in the same way as strategies like multilateralism, idealism, or unilateralism. Thus, option C, realpolitik, is the correct answer.
