This is a geopolitical clash of power. It's not about respective political regimes, it's about relative power and influence. If China liberalises tomorrow none of the fundamental issues will change and China will still be a threat to the US. The only thing that will change is that the US will have to find something else in order to label China 'evil'.
Cite please. And won't the best way to debunk the "propaganda" be to just liberalize right? So ... everybody is waiting and has been waiting for decades, China should stop making excuses and get on with it.
The US destroyed Bolivia, replacing an elected government that was legally found to be allowed to run, with a far-right nationalist military-backed junta that refuses to hold elections : https://en.wikipedia.org/wiki/2019_Bolivian_political_crisis
The US installed a brutal dictator in Chile, with the coup killing the legitimately elected president and overthrowing the liberal democracy, replacing it with dictatorship : https://en.wikipedia.org/wiki/Salvador_Allende
No, it is entirely clear to anyone in the world that the US will destroy your country and kill you if you oppose, no matter how liberal it is, if it suits their geopolitical interests.
Iran had no democracy. Mosaddegh was appointed Prime Minister by the Shah, he was not democratically elected by the people of Iran. The Majlis that nominated him were a collection of feudal lords that dominated Iranian politics, they were not democratically elected by the people of Iran, they co-ruled Iran as a feudal kingdom.
If Iran were a democracy the Shah wouldn't have been appointing the Prime Minister.
It has been 40 years, and just look at Iran today: zero human rights. You're going to try to blame the US for four decades of theocratic dictatorship? Laughable. The timer on that excuse has long since expired. Iran is responsible for the condition of Iran today, and the people that installed the theocracy are solely responsible for that too.
> The US destroyed Bolivia, replacing an elected government
That's an entirely false, invented claim. Which is why you didn't even try to support it.
