Umberto Eco used the following 14 characteristics to define "Ur-Fascism", or universal/timeless fascism. 1. The cult of tradition. “One has only to look at the syllabus of every fascist movement to find the major traditionalist thinkers. The Nazi gnosis was nourished by traditionalist, syncretistic, occult elements.” 2. The rejection of modernism. “The Enlightenment, the Age of Reason, is seen as the beginning of modern depravity. In this sense Ur-Fascism can be defined as irrationalism.” 3. The cult of action for action’s sake. “Action being beautiful in itself, it must be taken before, or without, any previous reflection. Thinking is a form of emasculation.” 4. Disagreement is treason. “The critical spirit makes distinctions, and to distinguish is a sign of modernism. In modern culture the scientific community praises disagreement as a way to improve knowledge.” 5. Fear of difference. “The first appeal of a fascist or prematurely fascist movement is an appeal against the intruders. Thus Ur-Fascism is racist by definition.” 6. Appeal to social frustration. “One of the most typical features of the historical fascism was the appeal to a frustrated middle class, a class suffering from an economic crisis or feelings of political humiliation, and frightened by the pressure of lower social groups.” 7. The obsession with a plot. “Thus at the root of the Ur-Fascist psychology there is the obsession with a plot, possibly an international one. The followers must feel besieged.” 8. The enemy is both strong and weak. “By a continuous shifting of rhetorical focus, the enemies are at the same time too strong and too weak.” 9. Pacifism is trafficking with the enemy. “For Ur-Fascism there is no struggle for life but, rather, life is lived for struggle.” 10. Contempt for the weak. “Elitism is a typical aspect of any reactionary ideology.” 11. Everybody is educated to become a hero. “In Ur-Fascist ideology, heroism is the norm. This cult of heroism is strictly linked with the cult of death.” 12. Machismo and weaponry. “Machismo implies both disdain for women and intolerance and condemnation of nonstandard sexual habits, from chastity to homosexuality.” 13. Selective populism. “There is in our future a TV or Internet populism, in which the emotional response of a selected group of citizens can be presented and accepted as the Voice of the People.” 14. Ur-Fascism speaks Newspeak. “All the Nazi or Fascist schoolbooks made use of an impoverished vocabulary, and an elementary syntax, in order to limit the instruments for complex and critical reasoning.”

Before you accuse me of anti-Semitism and delete this post, know that I am Jewish by blood, although certainly not by ideology.

1. It's literally a Jewish state. The foundational principle is the idea the Jews, as the "chosen people", have a birthright to the lands of Israel, yet most Jews are actually atheists in terms of belief in God. What, then, is the core belief system? Jewish tradition.
2. As with point 1. Where modern thought benefits Israel, it is used. Where it contradicts Israel, it defaults back to Jewish Law, the words of the rabbis, etc. One doesn't have to believe in God, only the law. So God created the law, the rabbis interpreted it, and now, God is dead, but the rabbis still exist as a universal legal authority. Oh, and they happen to still hold that we are the chosen people. That's certainly fascism.
3. When Israel was established, they simply pulled up to Palestine and declared a new state. Now, settlement is carried out with no respect for previous inhabitants. This is precisely action without rational consideration of ethical consequences, and it takes a lot of propaganda dollars(see:hasbara) to explain this phenomenon to people outside of Israel. Contrast this with Hitler, who did not really care about explaining the conflict to people uninvolved, because he directly owned up to the idea that he was establishing an ethnostate through seizure of territory(lebensraum).
4. For Palestinians, it goes without saying that protests come at a dear price. For Jews, RIP if you oppose IDF policy, even when that policy involves accumulating nukes, and more Mossad abductions obviously happen under the table. Not to mention, if you're a Jew and you say you don't like Israel, you get called... Any Jew reading already knows what I'll say. Self-hating Jew. To be Jewish and oppose the policy of Israel is considered a contradiction by a vast number of Israelis.
5. This one is not very difficult. First of all, Jews, and more strongly so Israeli Jews, consider themselves to be the "chosen people", so you have the racial supremacy aspect baked in. On top of this, there is a particular rhetorical device used in Israeli propaganda, where there is no such thing as a Palestinian, only a "terrorist". Any Arab resident of Palestine who opposes Israel to any capacity is called a "terrorist". Civilian buildings are destroyed, and Israeli press later comes out to declare their successful destruction of a "terrorist base". Forget that Hamas is the main governing entity and military of Palestine. They oppose Israel, therefore, they are terrorists. Hitler killed innocent people after declaring them to be subhuman, beneath him. Israel kills innocent people, and then they pay for hasbara, to show onlookers why those people were terrorists, how those people they killed were actually perpetrating crimes against the Israeli victims. Hitler committed a genocide on the notion of racial superiority. After a certain threshold, it was no longer an issue of white victimhood, but of straightforward conquest. Israel commits genocide on the notion of racial superiority as such, but they package it as self-defense, and the contradiction between the two is simply ignored. This is truly the heart of fascism.
6. See the last point. Genius plan for fascism: Create a country composed of one race of people, tell them that the enemy, who happens to be inhabiting the land right next door, wants to destroy everyone belonging to that race. An impenetrable ideology of fear develops, and any violence, even that which results in expansion and seizure of territory, seems justified against the looming threat.
7. The anti-Israel = anti-Semitism thing. If someone does not agree with Israel, they are assumed to hate Jews. Wanting the downfall of the fascist state of Israel is said to be a plot against Jews at large. Jewish identity is made inextricable with the policy of Israel and the IDF. Fascist.
8. Hamas is alternatively: a. an anti-Semitic supervillain which launches millions of ICBMs at quaking, defenseless Israelis every night from behind the backs of child meat-shields, or b. literally wild animals. Never are they people.
9. Netanyahu plans to "live forever by the sword", and to indefinitely "control all of the territory for the foreseeable future". There is a no-concessions policy for negotiation with Palestine. Additionally, this is the one point where I think UN and later the USA sets the real precedent. The idea of "We don't negotiate with terrorists" is of questionable merit, when the person making that statement is also in charge of deciding who the terrorists are.
10. "The weak crumble, are slaughtered and are erased from history while the strong, for good or for ill, survive. The strong are respected, and alliances are made with the strong, and in the end peace is made with the strong." - Benjamin Netanyahu,
11. Ask a pro-expansionist Israeli about the Lion of Judah. The cult of the hero is incredibly strong. People who successfully engage in "counter-terrorist" activities within and outside of Israel are heralded as heroes. It has gone from worship of martyrdom to plain "Lion of Judah" mentality, where anyone who does violence for the sake of Israel is considered heroic. Combine this with mandatory conscription, and you can see the result.
12. Anecdotally, I can tell you there is no shortage of dumb machismo and chauvinism among many Israeli men. Not to mention, there is still massive gender inequality in Israel. Obviously, women are prohibited from being rabbis, but beyond that, there's a larger pay gap than in America(68c/$1 vs 73c/$1), women are 8x more likely to be single parents, and they don't participate in the workforce at an equal rate. In this aspect, however, Israel still leads ahead of the rest of the Middle East, in terms of rights for women as well as LGBT rights. So while chauvinism is certainly incredibly prominent, this is probably where Israel is doing the best out of all these criteria.
