From the Document: "Colombia, a key Latin American ally, endured half a century of internal armed conflict. Drug trafficking fueled the violence, funding left- and right-wing armed groups. Some analysts feared in the 1990s that Colombia would become a failed state, but the Colombian government devised a novel security strategy, known as Plan Colombia, to counter the insurgencies. Plan Colombia and follow-on programs ultimately became a 17-year U.S.-Colombian bilateral effort. [...] Congress appropriated more than $10 billion for Plan Colombia and its follow-on programs between FY2000 and FY2016, about 20% of which was funded through the U.S. Department of Defense. Since 2017, Congress has provided nearly $1.2 billion in additional assistance for Colombia. For FY2019, Congress appropriated $418.1 million in foreign aid for Colombia, which encompassed efforts to promote peace and reconciliation, assist rural communities, and continue counternarcotics support through the U.S. State Department and the U.S. Agency for International Development. Congress has signed two continuing resolutions for FY2020 appropriations, with FY2020 aid levels set to match FY2019 levels through late December 2019."
