A referendum, a violence crisis, an international force and then a transitional administration.
On 30 August 1999, East Timorese voters rejected the proposed autonomy arrangement and chose a transition toward independence. The United Nations records that pro-integration militias, at times supported by elements of Indonesian security forces, then launched widespread violence, looting and arson.
Indonesia accepted international assistance on 12 September. Security Council Resolution 1264 authorized INTERFET on 15 September to restore security, support the UN mission and facilitate humanitarian assistance.
Indonesia later recognized the referendum result, and Resolution 1272 created UNTAET to administer the transition. East Timor became independent in 2002.
The case has four separate clocks: warning, coercive protection, restoration of public administration and political settlement. Collapsing them into a single “intervention worked” judgment hides most of the history.
