Palau’s role at the centre of growing US military activity in the western Pacific moved into the diplomatic and legal spotlight this week, as Palauan president Surangel Whipps Jr. made a historic first state visit to New Zealand while a new Guam‑based think‑tank report warned that accelerated American militarisation is eroding local oversight and stoking widespread dissatisfaction.
The Pacific Centre for Island Security’s Micronesia Security Outlook 2025, released this month, says long‑standing environmental and sovereignty “guardrails” written into Palau’s agreements with the United States have been undermined by a rapid build‑up of infrastructure and operations. The Palau chapter was written by Jodean Remengesau, director of the Bureau of Agriculture in Palau’s Ministry of Agriculture, Fisheries and the Environment, who argues the US has fallen short of obligations under the Compact of Free Association to meet Palauan environmental standards.
Remengesau’s contribution documents specific incidents that have fuelled local anger. He alleges the US military cleared land on the state of Angaur to host the first site of a tactical mobile over‑the‑horizon radar without securing an environmental earthmoving permit or holding community consultations required by Palauan law. According to the report, debris from the clearing — described as “piles of shredded tree debris” — raised the risk of invasive coconut rhinoceros beetle infestation and was later dumped on nearby residents’ yards in a hurried attempt to address the problem.
The environmental fallout has also landed in the courts. In 2023, Angaur Governor Steven Salii filed suit against Palau’s central government, the Palau Environmental Quality Protection Board, the US government and US military contractors, alleging the clearing of 271,807 square metres of land in Angaur without environmental impact assessments or permits. The case underscores the wider tensions the report highlights between national development priorities, environmental safeguards and expanded foreign military use of Palauan territory.
Those tensions are sharpened by recent bilateral developments. Under the renegotiated Compact of Free Association, the United States pledged an US$890‑million package to Palau over 20 years, a funding cycle that began on October 1, 2023. The compact also solidifies US defence responsibilities for Palau, and the report notes the combination of increased budgets and strategic pressure means the US military is expected to make greater use of Palauan bases and facilities.
A flagship US project in Palau — a US$118‑million radar installation — is slated to be operational this year, the report says. It adds that an initial presentation of the shoreline radar as a single infrastructure for mutual use between Palau and US forces later revealed two separate installations, a development that has heightened questions about transparency and local consent.
Palauan officials’ outreach to partners such as New Zealand, exemplified by Whipps’s first state visit, looks set against this backdrop of domestic unease and geopolitical competition between the United States and China. The Pacific Centre for Island Security’s analysis warns that unless environmental and consultative processes are restored and strengthened, Palauans’ sense of sovereignty and control over their land and resources will continue to be tested as security dynamics in the region intensify.
