The ICJ pursues cases against states.
> Not one iota of attention of the court ever went to that.
The ICC only has jurisdiction over the territories and nationals of the State Parties to the Rome Statute. In the case of Israel, the actions are taken on the basis of alleged crimes in Palestinian territory, the same basis they have used for pursuing Palestinian crimes. They have not "changed their own statutes".
In the case of Daesh/ISIS, the court has issued statement that affirm that there are serious crimes involved, but pointing out that for those crimes taking place in Syria and Iraq, the ICC had no territorial jurisdiction because neither state were parties to the Rome Statute.
In the case of your examples of Daesh actions in Russia, Russia is also not a State Party to the ICC, and so it was Russias own choice to ensure that Daesh can not be pursued by the ICC.
> Sorry, any government EXCEPT the US and Israel are allowed to ask that.
The US and Israel are not parties to the ICC. They should have no expectation that a court they have explicitly refused to be part of will allow them control over how the court exercises the mandate given to it by those who are actually parties to the court.
> Or you could point out less serious, but ubiquitous human rights abuses that the ICC won't touch for various reasons. For example, every last muslim-majority state violates freedom of religion, a human right. Even Morocco and Turkey do [3] [4]. You will not hear the ICC on this issue.
The "various reasons" being that the ICC does 1) *not have jurisdiction over states, 2) the Rome Statute does not allow the ICC to pursue individuals for violating freedom of religion.
In other words: While I'd be all for protecting freedom of religion and for the ICC to be able to prosecute people preventing it, it is not a power the ICC has been granted by its signatories.
Effectively your complaints against the ICC all boil down to the ICC following its own rules about what its jurisdiction is and which crimes they are allowed to prosecute.
