In what ways did the legacy of U.S. involvement in the Vietnam War shape the conduct of U.S. foreign policy from early 1969 to early 1993?

1. Which U.S. leader from early 1969 to early 1993 had the greatest impact—regardless of whether that impact was beneficial, harmful, a combination of the two, or neither—on world affairs? Support your answer with examples and argument. Be sure to indicate why you are passing over other likely contenders for this distinction. (This last element, however, need not be very lengthy. A single paragraph, in which you indicate why one or more other leaders could be designated the most impactful but are not, will suffice.)2. In what ways did the legacy of U.S. involvement in the Vietnam War shape the conduct of U.S. foreign policy from early 1969 to early 1993? What challenges did that legacy pose for American leaders as they made foreign policy? How did American leaders try to meet those challenges?(Note: the terms “early 1969” and “early 1993” are designed to draw your attention to presidential administration that took office in early 1969 and the one that left office in early 1993—and all the administrations in between.)As with the first paper, your sources are the assigned readings and the course lectures. Once again, be sure to provide adequate citations, following one of the approved methods outlined in The Chicago Manual of Style or in Kate Turabian’s A Manual for Writers of Term Papers, Theses, and Dissertations. Information derived from course lectures should also be cited; a simple citation like “History 171D, Remote Lecture 10b” will do.
