Yes, cuz those countries have shitty electoral processes. If the democratic and voting rights of the country is strong, then there is literally nothing immoral with there being no term limits. In a way, adding term limits, is anti-democratic, cuz there can be one guy people really like and has proven themselves capable, yet "the rules" say they can't run again.
hmmm maybe, as long as it's president run system not prime minister run system, and not one party system. tho there are issues with two party system during emergency, which is why i also believe that when we become a galactic empire, we will go back to feudal system as it's faster than democracy when responding to emergencies
