From the Document: "Burma (Myanmar) has been embroiled in a low-grade civil war between its military, known as the Tatmadaw, and over 20 ethnic armed organizations (EAOs) as far back as 1962, when the Tatmadaw overthrew a democratically elected civilian government. In 2011, the Tatmadaw handed power over to a hybrid civilian-military Union Government based on a 2008 constitution largely written by the Tatmadaw. The Obama and Trump Administrations attempted to foster Burma's return to democratic civilian rule by supporting the Union Government and its current leader Aung San Suu Kyi."
