Not sure you are right. Take POTUS as example. 8 years is maximum. Not every POTUS is totally patriotic. Some young POTUS will need to think more about their after retirement career, wealth, social influences, family,,, etc. If their terms can be longer (say 6 years for 1 term), they may not make the same decision. I am against dictatorship. And, there need to be check and balance.
