first of all, please remind me what country you live in. for some reason i was thinking it was germany and i thought that they did have elections for the leaders there. but, being that i truly am somewhat ignorant (or very ignorant) of how other countries view government and how they operate - i need to be filled in on it. please don't judge me for this - it's just something i haven't read about as much. also, you almost need to live in a country to fully understand how it operates in reality - because sometimes what the 'law' is is sort of different than what actually happens (in all countries).
i feel like a leaf on a river - when it comes to witnessing all different presidents of usa since 8 years of age (when i became cognizant of government and it's effect on people). i vaguely remember when kennedy was shot. the quietness of johnson. the embarrassment of nixon. the somewhat fumbleness of ford. the charity of jimmy carter. the icon of ronald reagan. the iron fist of george bush sr. the almost too easy-goingness of clinton. and now, a similar tight hand on foreign policy by george bush jr. to his father. all these presidents gave me a taste of what power was to them. what made them 'tick.' i can't say that i 'idolize' any of them. they all have or had strengths and weaknesses that were completely human and fallible. non could be completely fair to all people at all times.
God, on the other hand, in my understanding, created us all to have different 'talents.' i do think some people are created with an ability to reason better than others - and thus rule better than some. what i respect the most in a leader is the ability to have good advisors and listen to them. as you say -most times absolute power corrupts. in the usa we have checks and balances, but right now - is a strange time. we know we can be spied on (much as other countries have spied on their own citizens ie. china, russia, korea...), we know that certain things are not according to the geneva conventions (guantanamo), we know that war was declared and will not be considered successful until we establish 'democracy' or a 'stable government?' when it seems that we cannot force this and it is eluding us much like vietnam and korea in iraq. we cannot 'vote' for a discontinuation of the war - and so the presidency holds a lot of power right now.
i don't know what exactly would happen if we pulled out right now. or, if God would bless our efforts either way. I think we have to have a complete return to God for Him to be directly involved in our affairs in a positive way. as i read the bible (esp. deuteronomy) i see the idea of blessings and cursings on nations for obedience or disobedience to a law that was given to the israelites. not the laws about sacrifice - but the laws about how to set up a government that pleases God. it seems so foreign to us that God allowed 'kings.' but, if he allowed kings, he must have realized it was a 'pattern' that was followed from His own soveirgnty (and the next highest was the king). this pattern was blessed under king David since he followed God and destroyed all the idols and false gods that people worshipped. today, people don't even know that they are often worshipping or following idols of silver, wood, stone, gold, whatever. statues, images, ideas.
if some ruler was to do that nowdays, people would think they were crazy. we are not used to the idea that there is one perfect law, one perfect God, one perfect peace that emanates from his Holy Spirit, that is able to bring peace to the entire earth (for all peoples). that's why Christ said 'my kingdom is not of this world.' if it were, people would have recognized Him when He came the first time. the second time, He's coming in power. We will realize from the occurances that are supranatural, that He is in absolute control whether we like it or not. And, He will return to rule the world as King of Kings, and Lord of Lords. We're not used to kings and obedience...but that is because we have not had good kings. we're used to wreckless advantage taken by rulers over their constituents. what if...what if we had a benevolent ruler that actually cared about us personally even more than any president that ever lived. what if He really knew how to solve problems of all peoples. maybe the idea of kingship wouldn't be so bad. especially if it lead to peace for EVERYONE. no more war. no more tears. no more huge graveyards of young men under 24. to me, this would be ideal.
