Of course the great irony of this scene is that neither of them speak English. They both speak American. American is a stupid language, where the word liberal has contradictory meanings. Don't blame me for this I would prefer it if we could have stuck to English. But we are where we are.
Anyway the key thing to understand about Weimar Germany and Israel is that they were both extremely unfavourable environments in which to establish Liberal Democratic governance. Carping at Weimar Germany and Israel is a bit like assigning a person an allotment in the middle of the Sahara and then complaining that his marrows are a bit on the small side. Its difficult to find words to describe the harshness of the environment for Liberal Democracy in Weimar Germany and Israel when compared to say Britain or Sweden. Regardless of whether you think the idea of a German or an Israeli nation state was a wonderful idea, pure evil or somewhere in between, these environments and their historical cultural context were almost designed to produce anti Liberal extremist forces.
Anti liberal forces that sought to undermine such liberal principles as
Democracy
Free Speech
The rule of Law
Freedom of Religion
Racial and Religious equality before the law.
Hence the fact that Itamar Ben-Gvir may end up as Security minister is a great credit to the Israeli system. Under the American system Itamar may well have ended up as President. If the Americans on the other hand had the Israeli system its possible that Trump might have led a parliamentary faction, maybe he could have been a minister, but its extremely unlikely that he would ever have got to be Prime Minister.
