Myanmar’s (Burma) military dictatorship, which seized power in 2021, suddenly is vulnerable to attack from the hodgepodge resistance forces loosely aligned under a National Unity Government. These forces are of two kinds: ethnic minority armies, sometimes referred to as the Three Brotherhood Alliance, that have a long history of opposition to the military government, and pro-democracy groups backed by the NUG that have come together since the 2021 coup. (A publication of Myanmar journalists in exile in Thailand lists 30 armed groups in all, 10 of which are ethnic armies).
