Step 1: Define doctrine and identify why a president would want to announce one. A doctrine is an ideological platform that a president uses to advance a policy towards a country or region in order to accomplish foreign policy goals for the United States, so you will need to expand on this theme.
Refer back to Assignment 1, and build on whatever doctrine you wrote about then. Say, for example, you selected the Truman Doctrine. Therefore, this is the only thing you will write about in Assignment 2 step 1.
Step 2: Select one country you wrote about in Assignment 1 and describe the Cold War relationship that existed between it and the U.S. Before the presidential doctrine was announced. In the case of Truman, you would pick either the Soviet Union, Greece, or Iran, since all three were affected by his doctrine. If you are writing about the Eisenhower Doctrine, you would choose Lebanon or Egypt; if you wrote about the Kennedy Doctrine, you would have write about Cuba or Vietnam; if your wrote about the Nixon Doctrine, you would choose either Vietnam, Saudi Arabia or Iran; if you chose Carter, you would select either Iran or Afghanistan; and if you wrote about the Reagan Doctrine, you would select Nicaragua, Angola, Russia or Afghanistan (although there were several others).
Step 3: Describe what effect the presidential doctrine you chose has had on regional or global affairs since it was announced during the Cold War. That is, how did the doctrine change the status quo regionally or globally after it was announced by the U.S.? What happened in Western Europe after the Truman Doctrine was announced? What happened in the Middle East after the Eisenhower Doctrine was announced? What happened with Cuba or Vietnam after Kennedy offered up his doctrine of flexible response? What happened in Southeast Asia or the Persian Gulf after the Nixon Doctrine went in effect? What happened in the Middle East after the Carter Doctrine was announced? What happened in Central America or Africa or the Middle East after Reagan announced his doctrine?
