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.

Is the future of humanity, autocracy? For the rest of humanity’s existence?
If your representatives aren’t in any way obligated to vote in accord with the wishes or best interests of the people they represent then it’s definitely not any kind of democracy
Well neither are your representative congressmen. Following that reasoning, only direct democracy is democracy?
