AAQ – I don’t think it is likely “zionist” fault, as they were a significant part of those who survived and prospered after that.
So did the Germans… No one claims to be able to fully understand how and why Hashem operates. We have a Mesorah that “punishment” is the result of “sin”. The Holocaust certainly qualifies as “punishment”. Many people bigger than you and me said Zionism qualifies as “sin”. If you don’t like it, zol zein gezindt. You are still a Yid, and so am I, and so is HaKatan.
