East Timor was originally colonized by the Portuguese, and remained a colony up until the fall of the military dictatorship in 1974. East Timor declared independence soon afterwards, but Indonesia soon decided to intervene as it became clear that the government of the new state would most likely be leftist. The Indonesian government began "Operation Komodo", which was intended to bring about the integration of the East Timorese territory. It began with a propaganda campaign, but after the outbreak of conflict in East Timor, the Indonesian military began a campaign on 7 October starting with an assault on a border post and accumulating with a full-scale invasion utilizing paratroopers and naval support. The United Nations quickly condemned the invasion via resolution, but due to resistance in the Security council, no further action was taken. The United States also tacitly gave their approval, as the dismantling of a pro-communist government helped advance the policy of containment being pursued by the government.
