An autocratic country could easily spread propaganda in the democratic country, because of “free speech” rules that most democratic countries have, but a democratic country cannot easily spread its propaganda in the autocratic country.
An autocratic country can buy an election in the democratic country, but the democratic country cannot easily coup an autocratic country.
Are all democracies are doomed to fail?
Is the future of humanity, autocracy? For the rest of humanity’s existence?
“countries” are invisible lines draw on a map by someone. Propaganda and lies are a tool used by people to persuade others, free speech and freedom are a natural condition upon which humanity can evolve and prosper.
