I noticed that in this and similar videos Bibi has volumes of the Talmud and other Jewish texts behind him. (Usually there is an Israeli flag as well, but not when the primary audience is Iranian!)
I discovered that when Bibi is speaking in Hebrew to his Israeli audience, in videos that are not meant for the rest of the world, his library is quite a bit different - secular Hebrew texts and an encyclopedia (I believe Encyclopedia Hebraica) but not Jewish texts.
Does he think that religious Jewish texts would turn off his Israeli audience? Very possibly.
And he seems to believe that the subtle message to give to the world is that Israel is where the Jewish people have been centered for millennia. (Also, he probably realizes that his Jewish support in the Diaspora is disproportionately religious and he wants to maintain that support.)
