Dutch Government developing compulsory military call-up system, Caribbean application remains unclear

GREAT BAY--The Dutch Government is actively developing a compulsory military call-up system that could be triggered if voluntary recruitment fails to meet Defense growth targets, but official documents reviewed do not yet show that the proposed Dutch system will automatically apply to St. Maarten, Aruba or Curaçao.

A review of official Dutch Government and parliamentary documents confirms that the Netherlands is working on what it calls a “selective call-up obligation,” or selectieve opkomstplicht, as part of plans to rapidly expand its armed forces.

The policy is tied to the Netherlands' goal of building a scalable military force. In an April 3, 2026 letter to the Second Chamber, State Secretary for Defence Derk Boswijk said Defense is working toward approximately 100,000 personnel by 2030 as a first step, while the broader estimated need is around 122,000 people. The Government's position is to remain with voluntary recruitment for as long as possible, but to prepare for other scenarios if growth falls too far behind projections or the security situation worsens.

The April letter sets out a five-stage “escalation ladder” showing how the system could gradually move from voluntary participation to compulsory military service.

The first stage involves a voluntary questionnaire and voluntary response to an invitation for a discussion. The second would make the questionnaire mandatory while keeping the discussion voluntary.

A third stage would require both completion of the questionnaire and attendance at a discussion. Under the fourth stage, young people could also be required to participate in selection and medical examinations, although actual service would remain voluntary.

The final stage goes further. It would require completion of the questionnaire, attendance at a discussion, participation in selection and medical examination, and mandatory reporting for service. The Defense letter describes the progression as moving from voluntary consideration of voluntary service to, in the final stage, compulsory consideration of compulsory service.

Defense said the exact criteria for selection, targeted groups and the circumstances that would trigger movement from one stage to another are still being developed.

The Government is also working on the legal framework required to support the system. According to the April letter, planned changes to the Kaderwet Dienstplicht, the Dutch framework law on conscription, are intended to make it possible to require completion of the Defense questionnaire and provide a legal basis for other compulsory stages.

At present, Defense continues to send a voluntary questionnaire to young people turning 17. The Government has said it wants to stay within a voluntary system as long as possible.

However, the official Spring 2026 State of Defense report, published by the Ministry of Defense on June 8, states that more far-reaching measures cannot be ruled out.

“Although we strive to remain in a voluntary model for as long as possible, it cannot be ruled out that more far-reaching measures, such as a mandatory questionnaire or some form of call-up obligation, may become necessary in the future,” the report states in Dutch.

The possibility of compulsory service has also been openly debated in the Dutch Parliament.

During the March 2026 Defense budget debate, MPs questioned the Government and coalition members about the link between the 2030 personnel target and a possible selective call-up obligation.

The debate referred specifically to the Government's position that if the targeted expansion of the armed forces is not achieved, selective compulsory call-up is one of the measures that may be considered. A coalition MP described it as a last resort if the necessary expansion cannot otherwise be achieved.

Boswijk told Parliament that further legislation would be required before changes could be implemented and that the matter would have to return to the Second Chamber. He said the final model had not yet been determined and would be further developed through Defense policy and legislative discussions.

The findings provide important context to a recent petition supported by organizations and activists in Aruba, Curaçao, St. Maarten/St. Martin and St. Eustatius opposing mandatory military enlistment and demanding clarification from Kingdom authorities.

The Caribbean groups have demanded immediate written clarification on the intent, scope and legal basis of the Dutch proposal, a guarantee that no compulsory military policy will be applied to the participating Caribbean islands without consultation and democratic consent, and a Kingdom-level dialogue on the constitutional, historical and decolonial implications of military policy.

The official Dutch documents confirm that a possible compulsory call-up is under active policy development. They also confirm that the 2030 military growth target forms part of the wider discussion.

However, the documents reviewed do not state that the Dutch Kaderwet Dienstplicht or the proposed selective call-up system will automatically apply to St. Maarten, Aruba or Curaçao.

An earlier official Dutch parliamentary explanation of the constitutional framework states that, under the Charter for the Kingdom of the Netherlands, conscription is a country matter. The document noted that conscription was separately regulated under Dutch law, the former Netherlands Antilles' Dienstplichtverordening 1961 and Aruba's own conscription legislation.

That distinction is important because St. Maarten, Curaçao and Aruba are autonomous countries within the Kingdom. The available official material reviewed does not establish that a Dutch change to its framework conscription law would automatically extend to the three Caribbean countries.

St. Eustatius falls into a different constitutional position as part of the Caribbean Netherlands. Official Dutch legislative history separately identifies the Dienstplichtwet BES as the conscription legislation for Bonaire, St. Eustatius and Saba.

The lack of clarity surrounding the Caribbean application of the proposed Dutch system could strengthen calls for formal clarification from the Kingdom Government.
