As a state party to the Genocide Convention, The Kingdom of The Netherlands files a Declaration of Intervention in the ICJ case of the Crime of Genocide in the Gaza Strip (South Africa v. Israel). Bravo. This means they support the case and South Africa. https://www.icj-cij.org/sites/default/files/case-related/192/192-20260311-int-01-00-en.pdf
I guess this is something every country that signed and ratified the Genocide Convention has already done and The Netherlands is late, but not too late. (Rhetorical question. I know many countries have decided to stay silent)
The first EU country to file an intervention was Spain, back in 2024. Ireland and Belgium were next. And finally The Netherlands. Hungary also filed one but you can guess in which direction that one goes. And that's all. No other EU member state filed. See all interventions at https://www.icj-cij.org/case/192/intervention
