Jewish fascism, not Nazism.
Nazism is, in part, defined by its anti-semitism and, while many of Israel’s supporters are anti-semitic (notably Christian Zionists but also those who insist that ‘real’ Jews support Israel regardless) it’s just not appropriate to identify Nazism as the form of fascism practiced by Israel. It is authoritarian and supremacist but it is not specifically Nazi.
Ur-Fascism is a good read.
Cork insulation would usually be skimmed over with plaster. You could have a look at insulatiing plaster too, but I think that needs to be thicker than cork to work well. Less munchable by critters though.
In an old building, you need to use breathable insulation, breathable plaster, and breathable paint (and breathable mortar, if you’re repointing the outside). The moisture needs an escape route.
