The fact that democracies make mistakes, isn't an argument against dictators having more carte blanche to make mistakes.

Any form of government is going to make mistakes.

By your very own logic, I could argue that dictators have more carte blanche to make correct choices, where democracies are mired down by compromises and too many cooks in the kitchen.

The possibility exists, but the reality is very different.

>"The fact that democracies make mistakes..."

Going to war and killing people is "a mistake". Let me rephrase it for you:

The fact that democracies are the same murderous criminal fucks when it suits their goals as are dictators. Yes the have more problem having their population to approve it but do they give a flying fuck?

These wars weren’t mistakes. The ruling class wanted them and got them.

There is nobody to admit a bad decision and reverse course on it?

Think of all the wars we didn't have :)

Democracies aren't perfect, but they can change, admit mistakes and adapt.

I think it is other way round.

In a democracy ideas are ingrained in public psyche for support. Be it Muslims/Jews/Christians good/bad, immigrants evil, abortion bad all become part of a large percentage of people's belief and changing that requires equally herculean efforts.

In autocracy, people are generally kept aloof of such decisions so you can always switch enemies from Eurasia to Eastasia and no one cares. In case of China, the value of Taiwan/Arunachal/... is mostly egoistical, based on some notion that Qing China boundaries must be restored. If tomorrow a new leadership comes and makes EU kind of setup with Taiwan, people will have no say and most won't care.

I mean Vietnam was stopped? And Afghanistan? Korea the US never started.
