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?
No they’re not.
Look around history over the global and democracies consistently are he most powerful because of the transparency that roots out corruption and the freedoms that allow scientific progress and capitalism that allows for strong economy.
Now before lemmies start down voting: yes, capitalism has its issues and it needs to be tempered by strong laws or you get whatever the hell the US is, but in principle allowing free trade is a huge boon to a country and it’s citizens
Free trade with a reasonable safety net for those at the bottom. The safety net also ends up acting as a minimum standard, why pay your entire wage to a landlord for a slum when the state will provide you with better accommodation for less?
