An international declaration of genocide is not only important to respect the brave soldiers of Ukraine but to show Russia that it can’t be a bully. How can it be fair that a country formed after surviving a genocide can be formally accused of genocide in a international court ?
After Russia started the invasion and started stealing children they were already isolated economically so why not bring the court case? They have an arrest warrant out for Putin but that appears different than the claim of “genocide” in regards to Israel.
China did not do anything after the UN report on Xinjiang came out, and many countries have already passed resolutions declaring the detention and sterilization of Uyghurs as genocide, but the ICC didn’t hear a case.
