Why? The only arguments made in it, are that she talks with the Israelis and that she does not stop arms sales to Israel. Foreign policy including banning arms sales requires all members to agree, which is not going to happen. Von der Leyen and no EU offical for that matter can do that. So her only crime is that she continued to have diplomatic relations with Israel, which is also the case for most other countries in the world.
The argument to charge her for that crime seems to me to be incredibly weak.
Nazis also eat bread like everybody else. Sometimes everybody else doing something is just because it is the normal thing to do. Talking with a Nazi, does not make you a Nazi.
She does call for immediate ceasefires, humanitarian breaks and so forth pretty often, has increased EU aid to Gaza and supported placing EU sanctions on Israeli settlers. Not exactly the sort of stuff happening in a genocide.
Von der Leyen is not a country, so the ICJ has jurisdiction over her. The ICC could do that, but so far they only went against Netanyahu and Gallant for crimes against humanity and war crimes. Most of those were related to Israel blocking food into Gaza, which von der Leyen actively opposed.
