Palau’s expanding role as a strategic staging post for U.S. forces has provoked fresh scrutiny after a new security report and a historic diplomatic outreach by Palauan leadership brought environmental and sovereignty concerns into sharper focus.
The Guam-based Pacific Centre for Island Security’s Micronesia Security Outlook 2025 says guardrails meant to protect Palau’s environment and sovereignty have been undermined by an accelerated U.S. military buildup that, the report argues, has too often left ordinary Palauans out of the loop. The Palau section of the report was authored by Jodean Remengesau, director of the Bureau of Agriculture in Palau’s Ministry of Agriculture, Fisheries and the Environment, who contends the U.S. military has “missed and fell short of fulfilling its duties and responsibilities under the compact” with Palau.
Remengesau points to concrete instances, most notably land clearing in the state of Angaur to prepare a site for a tactical mobile over-the-horizon radar system. According to the report, the U.S. military carried out earthworks without obtaining Palauan environmental earthmoving permits or holding the community consultations required by Palauan law. The clearing — central to a 2023 lawsuit by Angaur Governor Steven Salii — involved 271,807 square metres of land and is alleged to have been undertaken without the environmental impact assessments and permits mandated under domestic law. Remengesau also raises environmental health concerns, saying shredded tree debris from the works created conditions conducive to invasive coconut rhinoceros beetle infestation and was later dumped on residents’ yards during a rushed cleanup.
The legal action initiated by Governor Salii in 2023 names Palau’s central government, the Palau Environmental Quality Protection Board, the U.S. government and military contractors as defendants, alleging violations of Palauan environmental law and compact agreements. The lawsuit and the findings in the new Micronesia Outlook add legal and reputational pressure on both Palauan authorities and the U.S. as the islands absorb increased strategic activity driven by rising U.S.-China tensions.
The report also contextualises the shift: under the renegotiated Compact of Free Association, the United States committed an US$890 million assistance package to Palau spread over 20 years, a cycle that began on October 1, 2023. That financial reliance is cited as a factor that may constrain Palau’s manoeuvrability even as its territory is made available for expanded U.S. defence purposes. The U.S. military’s US$118 million radar project in Palau — expected to be operational this year — is singled out as a near-term milestone in the broader militarisation the report documents.
Separately, Palauan leader Whipps made a historic first State visit to New Zealand this week, a diplomatic move that observers say underscores Palau’s growing international profile and may reflect efforts to diversify regional partnerships as security arrangements deepen with the United States. The trip coincides with heightened scrutiny of how infrastructure and defence projects are implemented on Palauan soil.
The Micronesia Security Outlook 2025 frames these developments as part of a broader strategic trade-off confronting small Pacific states: gains in security guarantees and development assistance on the one hand, and erosion of environmental safeguards, local consent and traditional sovereignty on the other. With the radar installation imminent and the Angaur litigation unresolved, the coming months are likely to test whether Palauan institutions and external partners can reconcile security objectives with environmental law and community rights.
