Joining ASEAN in 1967: Small State, Large War
It is July 1967. You are the senior foreign ministry official in a small Southeast Asian state of 25 million people whose exports are rubber, tin, and rice. The Vietnam War is escalating, with more than 500,000 US troops in South Vietnam. Britain has announced withdrawal from east of Suez. Indonesia has just ended its Confrontation against Malaysia, and Singapore separated from Malaysia in 1965. Your country faces a low-level communist insurgency along a remote border and depends on foreign markets. Five states are preparing the Bangkok Declaration to create ASEAN. The draft contains no mutual defence clause, only pledges of economic, social, cultural, and technical cooperation, and a principle of non-interference. The United States would welcome a clearly anti-communist grouping; China denounces the plan as a US tool. Your president asks whether to join now, wait, or join with conditions. The army wants security guarantees; the trade ministry wants access to regional markets; the foreign ministry fears being dragged into the Vietnam War.
1. Assess the security benefits and risks of joining ASEAN in 1967.

The benefits are mainly political rather than military. ASEAN would give a small state a regular forum with Indonesia, Malaysia, the Philippines, Singapore, and Thailand, reducing isolation and building habits of consultation after Confrontation. It could lower bilateral tensions, improve trade and communication, and give the state a collective voice that neither Beijing nor Washington can easily ignore. The risks are equally real. The draft has no mutual defence clause, so the army would gain no guarantee against insurgency or Vietnamese spillover. Joining a grouping welcomed by the United States could be portrayed by China and local communists as alignment in the Vietnam War. Non-interference also means neighbours cannot legally help with a domestic insurgency. The security value is therefore confidence-building and regime legitimacy, not deterrence; the risk is rhetorical alignment without material protection.
2. Recommend whether to join now, wait, or join with conditions, and justify your choice with the constraints in the setup.

I would join now with conditions. Waiting would leave a small state outside the only emerging regional framework and allow Indonesia, Malaysia, and Thailand to shape rules without its input. But the conditions should be explicit: no formal military pact, strict non-interference, priority for economic and technical cooperation, and freedom to maintain existing bilateral security ties. This satisfies the trade ministry's market access goal and gives the foreign ministry a shield against being dragged into Vietnam. It does not satisfy the army's demand for guarantees, so the government must explain that ASEAN is a political forum, not an alliance. Joining with conditions also gives the state a platform to urge peaceful settlement in Vietnam without formally taking sides. The alternative, waiting for a stronger security clause, is unrealistic because the founding states deliberately avoided one.
3. Explain how ASEAN's principle of non-interference both protects and limits your state.
Read the worked answer
Non-interference protects a small state by making its regime, borders, and internal politics formally off-limits to stronger neighbours. It reduces the risk that Indonesia or Thailand will support insurgents or pressure domestic policy, and it allows the state to join a regional body without surrendering sovereignty. But the same principle limits the state: if a neighbour harbours insurgents or if Vietnam's war spills across borders, ASEAN cannot collectively intervene. It also constrains the state from asking ASEAN to mediate in its own ethnic or communist conflicts, because that would invite scrutiny of its internal affairs. The principle is therefore a shield against domination and a handicap against collective security. In 1967, the shield is more valuable than the handicap because the main danger is isolation and bilateral pressure, not a conventional invasion.
