In the mid-1980s, as Sri Lanka’s ethnic conflict moved toward a more dangerous phase, US intelligence analysts assessed that Colombo faced a difficult choice: pursue a negotiated settlement with Tamil militants or intensify a military campaign that Washington believed was unlikely to achieve a decisive victory.
Declassified Central Intelligence Agency documents from 1986 reveal a detailed assessment of Sri Lanka’s worsening insurgency, President J.R. Jayewardene’s search for military support, and the wider diplomatic risks surrounding possible US arms assistance. The reports described a conflict in which government forces were expanding their arsenal but remained constrained by weaknesses in training, leadership, intelligence, and strategy.
At the time, Sri Lanka’s Tamil insurgency had entered its third year and was growing stronger. CIA analysts estimated that about 7,000 insurgent fighters were active on the island, with another 3,000 undergoing training in camps in southern India. The insurgents were also supported by a wider international network providing financial assistance, equipment, and safe locations.
The most prominent armed group, the Liberation Tigers of Tamil Eelam (LTTE), was consolidating control in parts of the Northern Province while strengthening operations in the East. The CIA assessed that Tamil militant groups were moving their support structures closer to areas under their influence inside Sri Lanka and developing connections with international arms suppliers and radical organizations.
President Jayewardene’s government was pursuing a two-track approach: negotiations aimed at political settlement while maintaining military pressure. In May 1986, Sri Lankan forces launched operations against insurgent positions in the North, seeking to reopen roads and relieve pressure on government positions. According to the intelligence assessment, the offensive failed to produce major gains because of strong insurgent resistance, leaving government forces largely defensive afterward.
With battlefield progress limited, Colombo turned again toward negotiations. Jayewardene proposed granting greater authority to provincial councils, including control over police and local security units. Under the proposal, Tamil-majority areas in the North and possibly the East would receive greater regional control. However, he rejected the central Tamil demand to merge the Northern and Eastern provinces into a single Tamil-administered region.
The CIA assessment noted that negotiations faced obstacles from both sides. Tamil moderates showed some willingness to discuss political arrangements, while the LTTE and other hardline groups opposed proposals that fell short of their demand for independence. At the same time, conservative Sinhalese political forces resisted transferring significant authority away from the central government.
The intelligence reports concluded that any agreement reached by Colombo was unlikely to include the most powerful Tamil militant factions. As a result, Jayewardene was expected to return to the United States and other foreign suppliers seeking additional military assistance.
The CIA predicted that Colombo would argue for arms either to enforce a partial peace agreement or to pursue a military solution if negotiations collapsed. Possible requests included helicopter gunships, transport helicopters, patrol boats, armored vehicles, small arms, ammunition, communications equipment, and defensive systems to protect aircraft from possible missile threats.
Sri Lanka was also expected to seek expanded military training, particularly through US programs focused on counterinsurgency operations and technical skills such as helicopter maintenance. However, the assessment noted that Colombo was unlikely to request a visible US training presence inside Sri Lanka because of the political criticism such a move could generate.
The potential increase in American involvement carried significant risks, according to the documents. CIA analysts warned that greater US military support could increase the threat of attacks against American citizens, diplomatic facilities, and other US-linked targets. Although Tamil militants had previously avoided sustained attacks against US interests, the agency noted that insurgents had targeted foreign nationals, threatened multinational companies, and carried out attacks against economic facilities.
The reports also raised concerns about the international reach of Tamil militant networks. The CIA assessed that the LTTE maintained overseas connections and had developed capabilities that could support operations beyond Sri Lanka, including through networks in Europe and other regions.
A major concern for Washington was the potential reaction from India. New Delhi viewed Sri Lanka as part of its regional sphere of influence and was sensitive to outside military involvement on the island. CIA analysts warned that increased US military assistance could strain Indo-US relations, particularly if India believed Washington was expanding its influence in the Indian Ocean.
However, the documents also outlined the consequences of refusing Sri Lanka’s requests. A failure to support Jayewardene, analysts warned, could reduce US influence in Colombo and encourage Sri Lanka to seek military supplies from other countries, including nations in Europe, China, and Israel. The assessment suggested that regional governments could interpret a US refusal as a sign of unreliable support for partners.
A separate CIA memorandum from January 1986 examined whether Sri Lanka could achieve a military victory without major outside assistance. The conclusion was cautious: government forces lacked the capabilities required for a successful counterinsurgency campaign.
The report identified several weaknesses within the Sri Lankan security forces, including poor organization, limited training, weak leadership, inadequate intelligence, and the absence of a unified strategy. Although Colombo had increased weapons purchases and expanded military resources, analysts argued that these measures did not address the deeper structural problems affecting the armed forces.
The intelligence assessment also highlighted problems with Sri Lanka’s military buildup. Large portions of new defense spending were directed toward equipment purchases rather than training. The report noted that some acquisitions, including certain aircraft and heavy weapons, were poorly suited for a guerrilla conflict requiring mobility, intelligence, and specialized counterinsurgency tactics.
Meanwhile, the insurgents continued strengthening their position. The CIA assessed that Tamil militant groups had improved their weapons capabilities, replacing older rifles and homemade explosives with more advanced equipment, including AK-47s, M-16 rifles, and rocket-propelled grenades.
The agency warned that a renewed government offensive might achieve limited short-term gains but was unlikely to eliminate the insurgency. If government operations failed, militants could expand attacks against security forces and civilian targets, potentially spreading violence beyond traditional conflict areas.
By 1986, US policymakers were therefore confronted with a complex regional security challenge: supporting an ally seeking military assistance while avoiding a deeper conflict, worsening relations with India, or provoking broader militant retaliation. The declassified assessments show that Washington viewed Sri Lanka’s conflict not only as a domestic struggle but as a crisis with implications reaching across South Asia and beyond.
