Lots of people and countriesare claiming Russia is committing genocide and are investigating that possibility.
Several nations and legal institutions have also classed China’s actions against the Uyghur as genocidal.
However, as far as I’m aware neither Russia or China are signed up to the ICC so there’s not much point in using that body to penalise them.
Israel is though and your claim there’s no proof is literally true (in the sense you used the word ‘proof’) but there is plenty of evidence that Israel certainly has genocide very much in the forefront of their minds when members of the Israeli government suggest nuking Gaza, or creating ‘no go’ areas for Palestinians in recognised Palestinian areas that just so happen to be where Palestinian farmers grow and harvest food. Israeli historian of the Holocaust Omer Bartov warned that statements made by top Israeli officials “could easily be construed as indicating a genocidal intent.”
