This is one thing many forget, mostly due to drinking our own koolaid about the inherent superiority of liberal democracy. Authoritarian regimes almost by definition have high public support, because they couldn't function at all if even a relatively small proportion of society went against them. The people who want to overthrow them are either out of the country or insignificant. Dictatorship is impossible without populism.

This doesn't make any sense to me. There are and have been numerous authoritarian regimes that lack "high public support", now and in the past. The entire idea for most authoritarian regimes is to slowly minimize the power of those who oppose them. And then, they spend a huge amount of resources looking for dissent (SD/Gestapo, Stasi, etc.) and trying to control the societal narrative.

Any government that lacks public support collapses.

Democratic governments can operate without a plurality of support for the current government, because the population generally supports and is invested in the system of government. When democratic governments fail, there is usually very little danger of violence or economic and societal instability, because there is trust in those systems. Corruption and malfeasance harms trust in the systems of governance which democracies depend upon.

Authoritarian governments depend on confidence in the government to continue functioning. The system of government isn't necessarily trusted, the workers of government aren't necessarily trusted, but the leaders are in charge and doing things. Media manipulation and effective propaganda is certainly an important tool for these governments, but pointing out that it exists doesn't mean that it doesn't work! Propaganda totally does work, by almost all measures. Russia, China, Cuba, Iran all have high domestic support for the government.

Authoritarian governments also tend to be very stable - people know what to expect. Democracies change periodically. The stability and familiarity are key to the trust that authoritarian governments maintain. The protests in Iran prior to the current conflict are a good example of what happens when a government fails to maintain the trust of the people - the arrival of war saved the current regime from falling apart at the seams when Khomeini died of cancer in a few months and a squabble for the leadership broke out amid a collapsing economy.

I think that you're underestimating the power of authoritarianism. For Iran, I don't think the government was in any danger prior to the war. It was capable of exerting control through the state apparatus quite easily. And look at North Korea, you think that the people under that government are supportive? That's nonsense on stilts.

Also, that collapse you refer to can take an awful long time under authoritarian control.

I feel like this discussion is more about westerners who don't understand the actual effects of political repression. A reminder, Nicolae Ceaușescu had a 90+% approval rating just a week before he was put on trial and deleted in less than a day. Measuring approval ratings in authoritarian regimes is an almost impossible task if you care at all about accuracy.
