IT IS AN Argumentative essay. You must answer one essay question from the list below, presenting and developing a main argument and at the same time engaging with existing academic scholarship about US intelligence and foreign policy.
essay question:
How influential was the CIA during the Reagan presidency (1981-89)? 
In completing the essay assignment, you should address Module Learning Outcomes A, B, C, D, and E. You must engage with at least five secondary sources (scholarly books/book chapters/journal articles)from the sources I have uploaded. Failure to engage with those secondary sources will result in a two-mark penalty per missing source up to 10 marks. You are encouraged to supplement these sources with your own independent research of other English-language academic sources and to engage with primary source evidence (such as government policy papers and intelligence memoranda, speeches, memoirs etc.) 
You don’t need to find Secondary sources by yourself, I will help u to find and upload them.
Also let me preface this by saying that no false citations will be allowed to appear. Thanks.
