The destruction of America is viewed as the linchpin for the group’s nihilistic agenda. Israel is also a primary target of the group, but America is viewed as bearing the “primary responsibility for all of Israel's crimes.”

Ultimately, the group’s objective is not limited to Israel or confined to a single foreign policy grievance. Rather, it is the systematic erosion and eventual destruction of American power and legitimacy in the foreign arena and the dissolution of the country’s internal social cohesion.

Who is Unity of Fields?

Unity of Fields is the rebranded American branch of Palestine Action, a UK-based group founded in 2020 to promote and carry out direct and violent protests worldwide through targeted campaigns against defense and security companies that do business with Israel.

Using “disruptive tactics,” Palestine Action says it “challenges the corporate enablers of the Israeli state’s military-industrial complex and seeks to make it impossible for these companies to profit …”

Palestine Action

Palestine Action operates in a decentralized manner through “activist cells” that carry out acts of domestic terrorism. In the UK, the group has waged an escalating campaign of disruptive protests, vandalism and sabotage, primarily targeting Elbit Systems, an Israeli defense, security and aviation company, and the UK’s military and security infrastructure.

Members have also assaulted numerous police officers. At one protest alone, 17 officers were assaulted by Palestine Action protesters.

Cells have repeatedly broken into or occupied arms factories, company offices and related facilities, damaging buildings, machinery and vehicles with paint, hammers and other weapons.​

After the group infiltrated a Royal Air Force base in June 2025 and defaced two Airbus Voyager refuelling aircraft (part of UK’s national security infrastructure), the government moved against them.​

In July 2025, the group was designated a terrorist organization by the UK.

Palestine Action Rebranded

Palestine Action US was co-founded by communist and radical activist Calla Walsh. The group's earliest activity was its participation in a Nakba event on Capitol Hill organized by House Representative Rashida Tlaib in May 2023. Nakba, translated as “catastrophe,” is how Palestinians refer to the founding of the state of Israel in 1948.

The group went into high gear after the October 7, 2023, terrorist attack on Israel by Hamas. Its primary actions were vandalizing, obstructing and sabotaging Elbit facilities in Cambridge, Massachusetts and Merrimack, New Hampshire.

By February of 2024, Walsh was facing multiple felony charges, including rioting, property damage, conspiracy to commit criminal mischief, burglary and conspiracy to commit falsifying physical evidence following her arrests in two states after participating in violent protests at Elbit Systems in Cambridge, Massachusetts and Merrimack, New Hampshire.

Calla Walsh: A Study in Radicalization

Calla Walsh, who founded Palestine Action and spearheaded its foray into domestic terrorism in the U.S., grew up in Cambridge, Massachusetts. The daughter of Chris Walsh, a Boston University English professor, she attended the Winsor School, a top private school for girls in Boston requiring an annual tuition payment of more than $60,000.

Walsh’s activism began at the age of 15 due to her concerns about the “climate crisis.” In 2020, at age 17, she gained prominence for her organizing on behalf of Sen. Ed Markey (D-Mass.). She later appeared frequently in the media as a voice for young activists supporting Sen. Elizabeth Warren (D-Mass.) and Sen. Bernie Sanders (I-Vt.).

However, Markey’s support of Israel during Operation Guardian of the Walls left Walsh feeling betrayed. She claimed that Markey had “framed Israel’s violence as a ‘both-sides’ issue rather than calling it what it is: settler colonialism and apartheid.”

She briefly segued into activism with the Democratic Socialists of America (DSA), but that, too, proved not radical enough for her. By December of 2021, she had left the DSA.

Later, she would call DSA member and mayor of New York City Zohran Mamdani, a virulently anti-Israel activist, “Ziohran”:

In December 2023, shortly after founding Palestine Action US, Walsh wrote about her foray into electoral politics, stating, “The experience permanently disenchanted me … and made me question whether ‘accountability’ even exists for representatives of a capitalist, settler-colonial empire like the United States.”

She added. “I don’t work on campaigns anymore. History shows us that direct action, protest, and internationalist solidarity are far more effective strategies than appealing to the morality of elected officials who are in the pocket of the military-industrial complex.”

The same year, she dropped out of McGill University in Montreal.

Domestic Terrorism

In February of 2024, Walsh, now 20 years old, faced multiple felony charges, including rioting, property damage, conspiracy to commit criminal mischief, burglary and conspiracy to commit falsifying physical evidence following her arrests in two states after participating in violent protests at Elbit Systems in Cambridge, Massachusetts and Merrimack, New Hampshire.

In a November 2023 interview with the Real News Network, Walsh spoke about the criminal charges against her. “...when I was in jail,” she said, “what I was thinking was that I would be ready to do it again and again and again and again until we shut these factories down.”

Unfortunately, the criminal justice system will most likely encourage that. In Massachusetts, three felony vandalism charges and one disorderly conduct charge were dismissed in July 2025, ending the prosecution against her.

In Merrimack, the original felony indictments (including riot, conspiracy, burglary and related counts) did not go to trial and were reduced via a plea agreement.​

Walsh pleaded guilty to misdemeanours in New Hampshire and received 60‑day jail sentences with additional time suspended, plus conditions such as good behavior, community service, restitution and stay‑away orders from Elbit facilities.

Awaiting the determination of her charges, Walsh continued to post her extremism.

By late 2024, she had completed the 60‑day jail term and was posting her radical ideas.

In the summer of 2025, Walsh traveled to Tehran.

Walsh appeared on Iranian state television, stating, “We all have a duty, when we go back to the countries we came from, to share the truth we saw here and to struggle against Zionism and imperialism,” Walsh said. “Glory to all the martyrs! Glory to the Axis of Resistance! … Death to America! Death to Israel.”

She also weighed in on Charlie Kirk’s murder, posting that the murder was “great and all,” but lamenting that Elias Rodriguez, who shot two Israeli Embassy staffers to death on the streets of Washington, D.C. on May 21, 2025, didn’t get as much “celebration.”

In early 2026, while reports flooded in of Iranian anti-government protesters being shot in the streets by the Iranian regime, Walsh was still publicly defending the regime.

After the capture of Venezuelan dictator Nicholas Maduro by America, she used her outrage over the event to call for death against American soldiers.

Funding

In November 2023, James “Fergie” Chambers told Los Angeles Magazine that he had been paying the legal fees of Palestine Action members arrested in various demonstrations. Chambers also stated, “I chant death to America every day…Imperialism is the death of humanity.” Chambers is an heir to the family fortune of Cox Enterprises, and is reported to have inherited hundreds of millions of dollars.

According to the NH Journal, Chambers was the founder of a Marxist commune in the Berkshires. He was once a Catholic convert and outspoken abortion opponent who defended free markets, but now praises Russia’s Vladimir Putin and supports Moscow’s war against Ukraine.

He later moved to New Hampshire due to the state’s tax and firearms laws. Following the Elbit incident, Chambers has been living in Tunisia (which does not have an extradition treaty with the United States).

The NHJournal reported that “before leaving the country, Chambers was under FBI investigation. Walsh, described by critics as his acolyte, now travels internationally with no apparent restrictions.”

New Mission

Following Walsh’s release from prison in August 2024, Palestine Action US rebranded as “Unity of Fields.” The group defined its new mission as establishing an "Anti-imperialist propaganda front for the international popular cradle of resistance."

The rebranded group announced it was moving away from "passive solidarity" with Palestinians and moving to active participation in what it terms the "new front of insurgency" within the United States. This strategy involves the dissemination of "militant propaganda" designed to normalize illegal actions and encourage protestors to clash with law enforcement.

The group aims to encourage and mobilize “affinity networks” of radical, far-left anti-Israel organizations to carry out militant direct actions, i.e., vandalism, particularly targeting Jewish and Zionist institutions, universities and law enforcement.

On social media, the group shares and glorifies “anonymous submissions” that document and glorify these acts of violence, urging its followers to carry out similar acts. It posts manifestos of activists and manuals featuring instructions on how to take “direct action.”

The group’s name invokes the Houthi terrorist group Ansar Allah, as they explained, “The meaning of the unity of the fields is that we are all one hand, one leadership, one direction, one goal, and one approach, and any attack on any of the components of the Axis is considered a direct attack on us.”

“We don’t mean unity for unity’s sake, but the protracted struggle it will take to reach a principled, higher unity against the forces of imperialism, Zionism, and fascism,” they continued.

Following the name change, Unity of Fields was removed from Instagram, most likely for encouraging violence.

Objective: Civil War

As the 2024 election approached, Unity of Fields revealed its goal: to be an anarchist disrupter in society. On its website, the group wrote:

“The illusion of 'choice' in US elections is just that — an illusion. The choice is not between a greater and lesser evil, ‘Democrat’ and ‘Republican’ … the liberal and fascist wings of the empire … are all proudly united in their goal to preserve the global hegemony of the US-zionist death machine, the greatest evil this world has ever seen.

“Our real choice is between rejecting this political theater or falling for it … We choose revolutionary defeatism, which means turning the imperialist war into a civil war, or, in fewer words: BRING THE WAR HOME."

In October 2024, then-Senator Marco Rubio called on the Department of Justice to investigate the group for acts of domestic terrorism. The group, clearly spooked, subsequently posted, “Unity of Fields is not Palestine Action US or any sort of direct action group – we don’t do direct actions, we only report on them and receive anonymous submissions.”

The post clearly contradicted an August 28, 2024 post saying, “Palestine Action US is not over, but our platforms are transforming into Unity of Fields …” as well as the following post:

In July 2025, Walsh announced that she was no longer affiliated with the group after the organization “purged” her. “I complied with the decision and transferred them ownership of the accounts,” Walsh added.

The rest of the group remains anonymous.

Extremist Ecosystem

Unity of Field operates within a deliberately tiered structure composed of inside groups, outside groups, and militant groups. Each tier serves a distinct function while reinforcing the others, allowing the movement to exert pressure across political, cultural and physical domains simultaneously.

Inside groups pursue power from within existing democratic institutions. Organizations such as the Democratic Socialists of America (DSA) and the Council on American-Islamic Relations (CAIR) focus on electoral politics, candidate endorsement, policy influence, and institutional capture.

When not in positions of power, these groups operate as part of the activist front. They mobilize protests, leverage public outrage and expand their ranks through grievance-driven campaigns.

Electoral engagement and street-level activism are not competing strategies. They are mutually reinforcing components of a long-term project to reshape the state from within.

These inside actors work in close coordination with outside groups, which operate without the constraints of electoral legitimacy. Organizations such as Within Our Lifetime, Al-Awda, the Party for Socialism and Liberation and The People’s Forum reject canvassing and conventional political participation.

Instead, they function as radicalizing forces, identifying sympathetic politicians and pushing them further toward ideological extremism. Even when nominally aligned with those in power, these groups maintain an oppositional posture. They apply constant pressure through disruptive protests and public confrontation.

Arrests, when they occur, are overwhelmingly limited to low-level protest violations and today carry minimal long-term consequences. This reinforces a culture of impunity.

At the furthest end of this spectrum are militant organizations. These are groups that have concluded that institutional engagement and mass protest are insufficient. While their ideology, messaging and protest aesthetics closely mirror those of inside and outside groups, their tactics often escalate toward criminality and domestic extremism.

These organizations engage in coordinated vandalism, sabotage and property destruction, often resulting in tens or hundreds of thousands of dollars in damage. They openly incite criminal behavior, glorify violence and celebrate acts of terrorism and murder as legitimate forms of resistance.

Unity of Fields belongs squarely within this final category.
