Which works in long time scales as long as the players agree that they will play by the rules of democracy, aka respect the institutions. So democracy suffers from 2 main issues: 1) timeliness: some problems need to be solved now, not in 10 years. Example, need to decide your stance against Russia. 2) fragility from the inside: A malicious player can manipulate democratic institutions and convert it to an autocracy. See Russia, Turkey and Jan 6 USA. Not sure how one can design a system robust to these two threats.
