Calla Walsh is a radical-left activist based in Boston. Walsh is a member of numerous activist groups, including Massachusetts Peace Action, the Democratic Socialists of America, and the National Network on Cuba. She is a notable supporter of anti-Israel activism through Palestine Action US and the Boston, Massachusetts branch of the Boycott, Divestment, and Sanctions movement, BDS Boston. ¹²

In November 2023, Walsh was one of three pro-Palestinian activists arrested and charged with vandalism during a protest with Palestine Action US outside the Merrimack, New Hampshire office of Israeli-owned defense contractor Elbit Systems. ¹³ As of December 2024, Walsh was released from prison and posted on her X profile “Just got released, still catching up but – anyone celebrating the counterrevolution in Syria, no matter how much they do it under a progressive guise, is no better than a Zionist. Long live the sovereign Syrian Arab Republic. The Axis of Resistance will still triumph.” ¹⁴

In July of 2025, a video surfaced on X, formerly Twitter of Walsh in what she claimed was the International Revolutionary Guard Corps (IRGC) aerospace park in Tehran. Walsh explained in the video that this was “the greatest honor of [her] life,” praising Iran’s domestic development of military equipment. 0){ let parent=divs[divs.length-1].parentNode; let footer=divs[divs.length-1]; delete divs[divs.length-1]; for (let i=2; i
