The Australian Mathematical Society has just released a resolution about hosting the ICM in the USA [https://austms.org.au/advocacy/]. It reads, "The Australian Mathematical Society calls upon the IMU to reconsider Philadelphia in the USA as host venue for the 2026 ICM due to potential difficulties for international delegates to obtain visas to attend, the potential risks to international delegates arising from the activities of the USA’s Immigration and Customs Enforcement officers, and the potential dangers arising from the involvement of the host nation in current warfare."
Well done to the AustMS!
