The establishment of a special tribunal to prosecute crimes of aggression against Ukraine is facing financial challenges, particularly due to reduced support from the US. The tribunal, agreed upon by the Council of Europe and Ukrainian President Volodymyr Zelenskyy, requires significant funding from European nations, which are now concerned about their ability to finance it without US backing. The tribunal's operational costs are estimated at €75 million annually, with additional expenses for security and premises. Key European G7 countries are hesitant to commit to funding, complicating the tribunal's future.
