Petition to Move the 2026 ICM Out of the United States

   We, the undersigned mathematicians, call on the IMU to reconsider its decision to hold the 2026 International Congress of Mathematicians in the United States this coming July. We rely heavily on the important precedent set by the IMU in 2022 when it decided not to hold the ICM in Russia in the context of its war of aggression in Ukraine and the potential dangers associated with holding such a conference in Russia in regards to freedom of political expression and the safety of LGBTQ participants. In the wake of this past decision, there is simply no sound argument one could make that claims international participants are more safe at this iteration of the ICM than they would have been in Russia in 2022. 

 

   The current American government has demonstrated in no uncertain terms its unbridled hatred of immigrants. This stance has increased the risks of traveling to the US, as it is now a country on the verge of martial law and there is a serious concern that academics (or anyone) traveling to the US may be denied entry. Indeed, the French mathematical society has already chosen not to attend the conference for these very reasons. The US supreme court recently ruled that government agents can stop and question civilians about their immigration status based solely on racial appearance or what language they speak. There are numerous cases all around the country of American citizens being caught up in this dragnet, and released only after experiencing terrible brutality and extended detainment. The highly publicized murders of US citizens by border patrol and ICE agents on the streets of Minneapolis and Los Angeles have not stopped or even slowed the brutality. Systemic mistreatment of detainees by federal enforcement officers have continued unabashedly. We point to the recent case of Nurul Amin Shah Alam, a blind man who froze to death after being picked up by ICE officers and then subsequently abandoned miles from his home. And in Philadelphia, the proposed host city, Parady La died alone and without access to his family while in ICE custody in what is suspected to be (assuming one gives the government the benefit of the doubt that no intentional harm was caused to La) a case of severe medical neglect.  

 

This is the context in which the IMU is inviting mathematicians from all over the world, people who may not look to an ICE agent as though they “belong”, and therefore, people who may be subject to indiscriminate harassment and physical violence. And even if mathematicians from the 75 countries for which the current US administration has suspended visa processing are able to obtain conference visas, how can we expect such mathematicians to safely visit Philadelphia and engage fruitfully in the conference without fear of harm and unlawful detention? The IMU is irresponsible in its promotion of such risky behavior amongst the world's mathematicians, especially when over 40 countries have issued travel warnings to their citizens when traveling to and from the US

 

So if the goal of the ICM is to encourage a sense of international unity amongst mathematicians, the IMU would completely fail on its own terms were it to go through with its plans to host the conference in the United States. The impossibility of achieving this sense of unity comes not only from the actions the Trump administration takes within US borders, but also from its flagrant disregard of basic humanity all around the world. Thus, just as many mathematicians objected to Russia’s hosting of ICM on the basis of its invasion of Ukraine, we argue that the current American government disqualifies the US from hosting the ICM in 2026. Indeed, America’s role in destabilizing the world through widespread attacks include:

These actions can be under no circumstances deemed civilized, justified, or representative of the spirit of unity to which the ICM aspires. Indeed, when Trump’s secretary of War, Pete Hegseth, was interviewed about the United State’s most recent attempt to disguise the destruction of another Middle Eastern country as “liberation”, he proclaimed proudly that “the only ones that need to be worried right now are Iranians who think they’re gonna live.” 

We emphasize that the violence perpetrated internationally by the US government directly connects to the primary concern of safety and well-being of conference participants. Given that one of the highest ranking governmental officials of the host country expressed an intention to indiscriminately murder Iranians, one might forgive an Iranian mathematician (regardless of their personal political orientation towards the war and the stated goals of its initiators) for not feeling a sense of unity at a US-based ICM. 

 
For the sake of the safety of our community and in the name of genuine unity amongst mathematical scientists across the globe, we the undersigned commit not to participate in the ICM if it is to be held in the United States. And we urge the IMU to move the conference to a far more hospitable location, one that would grant the ICM the chance to succeed in its mission of fostering cohesion and solidarity between mathematicians.

Professional Societies & Scientific Organizations Endorsing the Petition:

  • Sociedad Cubana de Matemática y Computación (Cuban Society of Mathematics and Computing)
“The Cuban Society of Mathematics and Computing as a professional society of mathematical scientists, cannot in good conscience recommend participation in the upcoming ICM for Cuban mathematicians, if it is to be held in the United States as planned. Indeed, safe passage to and from the United States is not at all a guarantee. Cubans run the risk of not obtaining a visa if the ICM is held in the USA. Recently, the VI World Baseball Classic was held there, and 8 members of the Cuban sports delegation were denied visas to participate in that event. In the future we hope to engage as broadly as possible with the international mathematics community. To this end, we must prioritize the safety and well-being of our members."
  • Science for the People
"Science for the People stands with the more than 1800 signatories demanding a boycott of the 2026 International Congress of Mathematicians (ICM), currently scheduled to be held in Philadelphia, US., in July, unless the ICM is moved outside of the U.S."
  • Just Mathematics Collective
"Just as we supported efforts to boycott the 2022 ICM in Russia, we now affirm the efforts of the more than 2000 signatories on this letter who are demanding that the IMU move the 2026 ICM out of the US. Indeed, we are heartened to see such broad mobilization of mathematicians on behalf of the human rights of their colleagues in the US as well as the many people around the world, from Cuba to Iran to Palestine to Venezuela, who are directly experiencing the unrelenting violence of US imperialism."
  • AGHAM Advocates of Science and Technology for the People
"AGHAM Advocates of Science and Technology for the People, an advocacy group of STEM professionals and advocates based in the Philippines, expresses its full support for the ongoing petition to move the 2026 ICM out of the US. It is inspiring to see thousands and thousands of mathematicians and other STEM professionals across the world mobilize in different ways against US-led war and imperialism, and we are glad to be part of this growing global movement. We, alongside other Filipino STEM professionals, continue to call for a permanent end to the war in Iran, and stand in solidarity with the peoples of the world negatively impacted by the war."
  • Organização dos Trabalhadores Científicos (Organization of Scientific Workers)
"The Organization of Scientific Workers (OTC), based in Lisbon, Portugal, is a non-governmental association of scientific workers, university professors, researchers, and research support technicians, founded in 1979 and affiliated with the World Federation of Scientific Workers since 1980. It is guided by the principles of the correct application of scientific knowledge and technological advances to improve the living conditions of populations in general, and acts on a global scale in defence of peace, social stability, and the preservation of the natural environment. The OTC expresses its full support for the ongoing petition to transfer the 2026 International Congress of Mathematicians (ICM) out of the United States. Incitement to war, promotion of, and involvement in armed conflict have been, for the last two centuries, a distinctive pattern of behaviour of the major Western powers, including the former colonial powers. In this respect, the role of the United States of America has long been, and is particularly today, seriously disturbing. Furthermore, it should be added that the US has been pursuing a policy which, while clearly detrimental to the national interest, imposes severe budget cuts, affecting both prestigious research universities and various government agencies active in critical areas of social life. These cuts are also disturbing and should be brought to attention, given the known restrictions on academic freedom and, more generally, on freedom of expression itself."
