Select a president from the table, “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.AS SOON AS YOU SUBMIT YOUR PAPER IN WEEK 7, IT WILL AUTOMATICALLY BE SUBMITTED THROUGH A SOFTWARE TOOL CALLEDSAFEASSIGN, WHICH IS USED TO DETECT PLAGIARISM. AFTER YOU UPLOAD YOUR PAPER INTO THE WEEK 9 DROPBOX, YOU WILL RECEIVE A RETURN FILE FROMSAFEASSIGNTELLING YOU WHAT PERCENTAGE OF IT WAS COPIED AND PASTED FROM OTHER STUDENTS’ PAPERS OR FROM INTERNET SITES. IF YOUR READING IS HIGHER THAN 30%, I WILL RETURN IT TO YOU WITH A DEDUCTION OF POINTS AND INSTRUCTIONS TO PARAPHRASE THE HIGHLIGHTED PORTIONS UNTIL YOU BRING THAT PERCENTAGE BELOW 30%. A FAILURE TO DO SO WILL RESULT IN A FAILING GRADE FOR THE ASSIGNMENT.In the Student Center, I have also uploaded a ZIP.FILE that contains papers on every doctrine announced by an American president, so here is research already done for you. Please take advantage of it.
