The Cold War And Presidential Doctrines

Select a president from the table (LISTED BELOW) , “Presidents and Their ‘Doctrines,’” in Roskin, Chapter 4. Then write at least a six-eight-page paper on the doctrine that president used according to Roskin. Your research must include at least seven credible sources, apart from your textbook. Your paper must address the following:
Fully define a doctrine and identify why the president of your choice announced a doctrine while he was in office.
Describe the diplomatic doctrine the president followed, with reference to specific actions or events that occurred.
Describe the effect that the presidential doctrine has had on regional or global affairs since it was announced during the Cold War.
Cite at least seven reputable sources, excluding Wikipedia, encyclopedias, dictionaries, blogs and other material that does not qualify as reputable academic sourcework.
Your assignment must:
Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
NOT INCLUDE AN ABSTRACT but do include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
Acknowledge that graphs, tables, drawings and photographs do not count toward the length of the paper; only what you have written as text itself.
These are the choices for topics:
Truman ― the Soviet Union, Greece and Iran. Concentrate mostly on the SU, because Greece and Iran were sideshows.
Eisenhower ― Lebanon and Egypt in the mid- to late-1950s
Kennedy ― Cuba and Vietnam. You will have to mention the policy of flexible response and its strong emphasis on counterinsurgency warfare, so just Google ‘Kennedy flexible response.’
Nixon ― Vietnam, Saudi Arabia and Iran. All three were critical components of his doctrine, but the last two were part of his ‘Twin Pillar Policy,’ so Google that.
Carter ― Iran and Afghanistan only
Reagan ― Nicaragua, Angola, Russia and Afghanistan (although Nicaragua and Afghanistan were the two most important, so focus primarily on these).
