Google DeepMind Engineer Resigns Over Gemini Military Deals

A Google DeepMind research engineer resigned on October 20, 2026 after failing to convince executives to end Google's involvement in Israeli military operations and new Pentagon partnerships, according to reporting by openDemocracy and techpolicy.press. Sophia Liguori, 32, has now gone public with her account and breached a lifetime non-disparagement agreement to publish her resignation letter.

Liguori worked in Google DeepMind's London-based Impact Accelerator team, which focused on sustainability applications such as optimizing electricity grid power flow. She says she was unaware of Project Nimbus—a $1.2 billion Google and Amazon Web Services contract with Israel signed in 2021—when she joined the company in May 2023.

What is Project Nimbus?

Project Nimbus provides cloud infrastructure to Israeli government entities. Its contractual terms prevent Google or AWS from denying service to any government body. Google has stated the work is "not directed at highly sensitive or classified military workloads relevant to weapons or intelligence services."

That statement sits uneasily with training materials leaked to The Intercept in 2022. Those materials showed the full suite of Google Cloud AI tools—including face detection, object tracking, and sentiment analysis—was available to Israel's Ministry of Defense.

In early 2025, weeks after Donald Trump's second term began, Google updated its AI Principles to remove prohibitions on weapons and surveillance applications. DeepMind chief Demis Hassabis and research labs senior vice president James Manyika wrote that "democracies should lead in AI development, guided by core values like freedom, equality, and respect for human rights."

What did the Lockheed Martin deal actually cover?

The classified-work question sits at the center of the dispute. openDemocracy reports that Google announced its Gemini models would be used for "both classified and unclassified purposes at the AI factory of Lockheed Martin," a primary U.S. defense contractor that builds military aircraft, missiles, and satellites.

The public record is narrower. A Google Cloud press release dated October 29, 2025 confirms a "strategic collaboration" to integrate Gemini into the Lockheed Martin AI Factory via Google Distributed Cloud, deployed in "secure, on-premises, and air-gapped environments." The release specifies that the first phase covers an "unclassified on-premise environment." It does not mention classified deployment.

Liguori's own account also addresses other expansions, including a June 2026 partnership with military contractor Palantir. She told openDemocracy: "You never know then how your technology will be used in Palantir's systems."

How deep does the Pentagon relationship go?

According to openDemocracy, in late April 2026 Google signed a contract with the US Department of Defense—styled by the report as the Department of War—allowing the Pentagon to use Google AI for "any lawful government purpose," including "mission planning and weapons targeting." The contract details have not been independently confirmed by public documents.

The deal triggered internal dissent at scale. Liguori and over 600 colleagues petitioned CEO Sundar Pichai to oppose the partnership. The petition received no response, according to the reporting.

Liguori's resignation letter pulls no punches: "I no longer believe that our technology will have a net positive impact on society... it's not this type of general-purpose AI we are racing to develop."

Why did Google change its NDAs?

Multiple UK-based Google employees who left on ethical grounds were bound by lifetime non-disparagement agreements. Liguori broke hers to publish her letter. This week, Google told UK staff it would not enforce the post-termination non-disparagement clause.

A spokesperson told The Washington Post the company had "updated our terms for new hires, which included removing the post-termination aspect of non-disparagement clauses." The change follows organizing by DeepMind members of United Tech and Allied Workers (UTAW) alongside No Tech for Apartheid and whistleblowing nonprofit Psst. It also coincides with the UK's Employment Rights Act 2025 taking effect.

What remains unconfirmed?

Google had not responded to openDemocracy's request for comment at time of publication. The October 2025 press release describes only unclassified deployment in phase one. Whether classified deployment has begun, is planned, or was merely aspirational in internal announcements is not confirmed by public documents—leaving the gap between Google's internal messaging and its public paper trail as the story's central open question.
