Interpreting Article 9 and Self-Defense: A Constitutional Judgement
A fictional country's neighbor launches a missile that passes over its territory and lands in the sea. The country's constitution (modeled on Japan's) renounces war and says land, sea, and air forces 'will never be maintained.' The government has long held that a minimum force for self-defense is permitted, and that force may be used only when three conditions are met: there is an imminent and illegitimate act of aggression against the country; there is no other appropriate means to repel it; and the use is limited to the minimum necessary. The cabinet must decide whether to (A) do nothing, (B) strengthen purely defensive measures such as interceptors and shelters, or (C) strike the launch site in the neighbor's territory.
1. Apply the three conditions to option C and explain the judgement.
Read the worked answer
Condition 1 (imminent and illegitimate aggression): a missile overflight that lands in the sea may not by itself be an 'imminent' attack on the country; further evidence is needed. Condition 2 (no other appropriate means): interceptors and shelters (option B) are an alternative means, so C fails this test unless B is shown inadequate. Condition 3 (minimum necessary): striking a launch site in another country's territory is not minimal if the threat can be met defensively. Judgement: under the stated doctrine, C is hard to justify for a single overflight; B is the constitutionally safer response. The reasoning turns on the conditions, not on whether the constitution 'allows an army' in the abstract.
2. How does the 'never be maintained' clause coexist with option B? Explain the interpretive move.
Read the worked answer
A literal reading of 'will never be maintained' would forbid even B. The established interpretation reads the clause together with the preamble's aim of security and the right of self-preservation, holding that 'minimum necessary force for self-defense' is not 'war potential' in the prohibited sense. So B (interceptors, shelters, warning systems) is permitted as self-defense, while power-projection abroad is not. Judgement: the clause is interpreted as prohibiting war-making capacity, not all defensive capability. This is a contested interpretation, so a good answer states the reasoning and acknowledges the dispute rather than asserting one reading as fact.
