Mattie Krop

On June 13, 2025, Krop was arrested at a protest against U.S. Immigration and Customs Enforcement (ICE) in Los Angeles and charged with criminal trespassing, according to socialistmajority.com.

On August 13, 2025, Krop was featured in a DSA video on Instagram where she said [00:00:53]: "We know that what happens abroad is always going to come back home. They train our police officers, help militarize them... Israel is our colonial outpost. They're there to ensure that we have power in the world to maintain our hold on the resources of the Middle East."

The accusation that Israeli law enforcement teaches American police brutal tactics during police exchange programs is used to demonize Israel. Participants in these programs have stated that the training in Israel focuses on public policy, counterterrorism and leadership training in the form of lectures and discussions.

The terms "empire" and "belly of the beast" are both euphemisms that anti-American activists use to describe the U.S. To learn more, see Canary Mission's campaign Bringing the War Home.

In April 2026, Krop signed a letter from DSA members calling for an arms embargo on Israel. The letter referenced Israel's "genocide against Palestinians and its regional war of annexation and regime change in pursuit of Greater Israel."

The term “genocide” was coined in 1942 and first used at the Nuremberg Trials of Nazi war criminals. Since Israel's founding in 1948, anti-Israel activists have accused Israel of "genocide" in an attempt to compare Jews to Nazis and delegitimize the creation of a Jewish state in the Land of Israel.

“Greater Israel” is a conspiracy theory which claims that Israel plans to expand its territory to encompass most of the Middle East and chunks of North Africa.

On August 17, 2026, Krop posted on Instagram a photo of herself posing with Karl Marx's book, "Capital."

Karl Marx is best known as the principal architect of Marxism and the foundational thinker behind communism and socialism.

On June 2, 2026, Krop posted on Instagram a quote from Vladimir Lenin's book, "What is Internationalism?" The quote read: "And since the war remains an imperialist war (both under a monarchy and under a republic) irrespective of the country - mine or some other country - in which the enemy troops are stationed at the given moment, recognizing defense of the fatherland means, in fact, supporting the imperialist, predatory bourgeoisie, and completely betraying socialism."

Vladimir Lenin (1870-1924) was the communist leader of the Bolshevik Party. He founded Soviet Russia in 1917 and was its dictator until he died in 1924. He was the dictator of the Union of Soviet Socialist Republics (USSR) in 1922-1924.

On April 24, 2026, Krop organized a Block the Bombs phonebanking party and social for DSA-LA's PSC. The event website said: "It has been nearly 900 days since the current onslaught in Palestine began and 78 years of ongoing occupation and genocide in Gaza and the West Bank..." and called for an end of American military support to Israel.

The modern State of Israel was founded 78 years earlier in 1948.

Anti-Israel activists spread antisemitism by denying Jewish history and religious rights to the Land of Israel in order to portray Jews as foreigners. The goal is to delegitimize restored Jewish sovereignty and justify terrorism. Terms they use include accusing Israel of "colonialism," "occupation," and "imperialism."

On April 1, 2026, Krop was listed as an organizer of an arms embargo subcommittee meeting that aimed "to pass legislation preventing the transfer of weapons and aid to countries credibly accused of committing crimes against humanity. You must be a Member in Good Standing to attend."

On February 18, 2026, Krop was listed as an organizer of a PSC meeting during which the committee's strategy for the year would be developed.

On February 13, 2026, Krop was listed as an organizer of PSC's "SOCIAL-ism" event.

Democratic Socialists of America (DSA) is America’s largest socialist organization. Its core ideology includes anti-American, anti-Israel, anti-Western and abolitionist elements. In August 2025, DSA passed “For a Fighting Anti-Zionist DSA,” making support for Israel an expellable offense. DSA has also called to “abolish I.C.E. and capitalism.”

Following the October 7, 2023, Hamas terror attacks against Israel, DSA condemned Israel, expressed support for Hamas, endorsed anti-Israel rallies and called for members to engage in anti-Israel activism. It condemned Israeli retaliatory attacks against the IRGC and Hezbollah, as well as the U.S. attacks against the Houthi terror organization, whose slogan reads: "...Death to America / Death to Israel / A Curse upon the Jews...”

DSA first endorsed the anti-Israel Boycott, Divestment, Sanctions (BDS) movement in 2017 and it has also condemned sanctions against countries like Iran and Cuba.

The group endorses far-left politicians on the local, state and federal levels. DSA also promotes anti-Israel agitators, including DSA members Rashida Tlaib, Zohran Mamdani and Linda Sarsour.

Young Democratic Socialists of America (YDSA), DSA’s youth section active in high schools and colleges, has co-organized anti-Israel protests across the U.S. since October 7, 2023, particularly the April 2024 pro-terror encampments on university campuses.

On October 7, 2023, Hamas murdered approximately 1,200 Israelis, kidnapped 251 and wounded thousands. War crimes included various systematic sexual crimes like gang rape and genital mutilation. Men and women were violated, even after being murdered. Victims who survived that day, including hostages, endured forms of humiliation and torture.

Gazans working in the targeted Israeli villages provided intelligence to Hamas on which families to kill and torture, including long-time employers. Many Palestinian civilians joined in and celebrated the attacks. Hamas livestreamed their crimes on social media, including to victims’ accounts for families to see. To learn more, see the Canary Mission page on Hamas.

The Boycott, Divestment, Sanctions (BDS) movement was founded by pro-terror activist Omar Barghouti in 2005 to turn “Israel into a pariah state, as South Africa once was.” Barghouti has also called for Israel's destruction and the BDS movement demands would result in that same goal.

BDS initiatives include calling on institutions and individuals to divest from Israeli-affiliated companies, promoting academic and cultural boycotts of Israel, and organizing anti-Israel rallies, protests and campaigns.

The movement’s most notable achievement has been infiltrating university campuses through lobbying for “BDS resolutions.” In these cases, student governments propose resolutions to boycott or divestment from Israel or Israeli-affiliated entities. BDS activity is often aggressive and disruptive. It has been noted that universities that pass BDS resolutions see a marked increase in anti-Semitic incidents and pro-terror activism on campus.
