PALAU — A new Guam-based security report and a historic diplomatic trip by Palau’s leader have sharpened scrutiny of the United States’ expanding military footprint in the island nation, raising fresh concerns about environmental protections, community consultation and national sovereignty as a major U.S. radar installation nears activation.
The Pacific Centre for Island Security’s Micronesia Security Outlook 2025 argues that safeguards written into agreements with the United States have been weakened by an “accelerated military buildup,” leaving ordinary Palauans insufficiently informed or consulted. The Palau chapter was authored by Jodean Remengesau, director of the Bureau of Agriculture in Palau’s Ministry of Agriculture, Fisheries and the Environment, who writes that while the Compact of Free Association grants the U.S. military exclusive use of Palauan land, waters and airspace, the treaty also obliges U.S. forces to meet Palau’s environmental standards — obligations he says have been missed.
The report recounts specific incidents that have stoked local dissatisfaction. It says the U.S. military cleared 271,807 square metres of land on Angaur for the first site of a tactical mobile over-the-horizon radar system without obtaining an environmental earthmoving permit or holding required community consultations under Palauan law. Remengesau’s section details how shredded tree debris left at the site invited infestation by invasive coconut rhinoceros beetles and was subsequently dumped on residents’ yards in what he describes as a “rushed effort” to respond — actions the report says the compact’s environmental stipulations were designed to prevent.
The dispute crystallised into legal action in 2023, when Angaur Governor Steven Salii sued Palau’s central government, the Palau Environmental Quality Protection Board, the U.S. government and its military contractors, alleging violations of Palauan environmental laws and compact agreements over the Angaur clearance. The lawsuit is cited in the report as evidence of growing local pushback against how projects have been implemented.
The heightened scrutiny comes as the United States has already pledged significant long‑term support to Palau under the renegotiated compact: an US$890 million package spread over 20 years that began on October 1, 2023, and includes a U.S. defence commitment. The report cautions that Palau’s heavy reliance on compact funds and foreign aid increases the likelihood that U.S. military use of Palauan territory will expand — a dynamic that appears set to become more tangible with the imminent operational status of a US$118 million U.S. radar project expected to be up and running this year.
Palau’s diplomatic posture has also shifted: President Whipps this month made a historic first State visit to New Zealand, underscoring Palau’s efforts to broaden relationships in the region even as security arrangements with the U.S. deepen. The PCIS report frames such outreach and the domestic legal challenges as part of an intensifying debate in Palau over how to balance strategic partnerships with environmental stewardship and local sovereignty.
Analysts say the timing of the report — coupled with the legal proceedings and the pending activation of the radar system — elevates the political stakes for Palauan leaders and for U.S. planners. If environmental and consultation shortcomings identified by Remengesau and litigated by Governor Salii are not addressed, the report warns, community opposition may complicate implementation of security projects and fuel broader regional unease about the environmental and sovereignty implications of great power competition in the Pacific.
