Seriously, what Israel is doing today is no different from what the Nazis did before and at the beginning of World War II, extreme nationalism, illegal expansion, annexation of foreign territory claiming it historically belongs to them, propaganda using the latest technology, terrorizing neighbors, military at the center of society.
Zionism unlike the Nazis is not a threat to western democracy. They want a Jewish state in the Middle East, which is not part of the West. As long as the West is not involved, it usually does nothing or just some arms export bans on the countries and some sanctions on leaders. Currently that is happening in Sudan, which is about as bad as Gaza, but has really nothing to do with the West. There is nothing about it in the news at least in the West.
The real intressting part is more that the West is not sitting on the sitelines, but is somewhat aiding Israel. It obviously depends on the country and some do not do it at all. However even so, you see Western countries moving away from Israel. All but the US that is.
The only thing that might be “surprising” for some in the support for Israel by Governments in the West (not to be confused with the general population, which just about everywhere seems to be far more anti-Genocide than the politicians) is how it massivelly contrasts which the last decades of talk of Freedom & Democracy from the politicians as well as the long running official posture towards the last bunch of Genocidal Ethno-Fascists - the NAZIs - which was mainly justified on their ethnic cleansing atrocities.
For those who all along were suspicious of the former words being nothing more than self-serving propaganda from some Western nations to excuse them de facto imposing their will on the people of other lands, usually to take their stuff (most commonly, Oil), and the latter being the useful parts of the truth whilst the inconvenient parts (like, for example, how Churchill himself was a Genocider or how the US profited from the War and only really entered it because of the Japanese attack on Pearl Harbor) were as much as possible not talked about, none of what’s going on is surprising, except perhaps the pleasant surprise of the reactions of the actual population (not the politicians, especially not the governing ones) in several such countries, often going against the will of the power elites and the heavy propaganda being deployed to convince them otherwise (for example, for all the Genocide-support of the UK Government and the BBC, not that long ago there was a demonstration with half a million Britons against the Genocide - think about it: 1.5% of the British population came out in a demonstration which is entirelly for the good of somebody else, not themselves, so 100% a question of Principle).
The politicians in general are and always have been Sociopaths, but on this which is a massive issue of Moral and Principle (it’s hard to come up with a stronger issue of Moral and Principle than the mass murder of children), most of the population are not Sociopaths nor are they following the Sociopaths, even in those countries were they are swamped by pro-Genocide Propaganda, some of which quite subtle and using techniques from Psychology to try and manipulate people’s perceptions.
