Very insightful.
The Jewish problem with Pius, IMO, isn’t with his personal actions or the actions of the Church in general at that specific time, it is more generally with the historic Jew-hate and more recent anti-Israel stance taken by the Church. Pius seems caught in the crossfire, so to speak.
They are very uneasy with Catholics in general, and you may be right that Pius XII is more of a convenient target than an actual offender.
