This essay covers a conference that explained some of the issues that plagued Latin America today and in the 20th century. The first part is about problems with brazil's higher education policies. The second part is about the origins of Columbia's War on drugs that still existed to this day. A more extensive explanation is written since the War on drugs involved US foreign policies during the Nixon administration.
