Only Need One!

Back then, when I was a child, I was wondering about something. To be a president candidate, I'm pretty sure that one has to be very competent. My country always has so many president candidates, but only one will be elected. So where do the others go? Why don't they use those unelected candidates? What a waste of competent human resources. Now I finally figured it out, not exactly now, I figured it some time ago (even though it might be not the correct answer).

Titanic, the ship that was believed to be unsinkable sank during its maiden voyage. Yeah, since it was the greatest ship at the moment, they thought that 1 captain might not be enough to handle that enormous ship, so they assigned 2. It's a great decision, until the Titanic, encountered the iceberg which would eventually sink it.
One of the captain yelled out "Turn left, there are some smaller icebergs on the right side", the other captain said "No, turn right, the current on the left side is too strong, and our position is closer to the right of iceberg, our chance of avoiding it is better". "No, I said turn left, even if we avoid that iceberg, there will be smaller icebergs, the current won't matter, this huge ship will be strong enough". "No, turn right, I'm more experienced than you, and from my experience, I believe right is a more viable choice". So they argued, the ship didn't turn anywhere, it went straight, and by the time they stopped arguing, it was already a hit.

There are 2 kingdoms that are currently on war. One of the kingdoms decides to launch a campaign, to end this war once and for all. This kingdom has 2 grand generals that have won the kingdom so many wars. It can't be said that one of them is better than the other one, they are just so great. The soldiers respect them both equally. Since this is not a usual campaign, the king decides to entrust the campaign to these two generals. As expected, they keep winning the wars. But after so many wars, the amount of soldiers decreases drastically, and they are all physically and mentally tired. Then comes the next war, they are ambushed, they are losing, they are outnumbered.
"Fall back soldiers, we'll do our best to survive for now, we'll strike back next time", one of the general says. "No, we'll fight back till our last breath, we have our pride, and we won't lose", the other responds. "We are outnumbered, our soldiers are tired and worse, we are ambushed, it's obvious that we have to give up this one, there is no point to sacrifice lives for a battle with no chance of winning". "There is no way back, our route of escape has been cut, beside, this is our chance to end the war once and for all, they might outnumber us, but they have lost so many battles, their morale is low, we will win, strike soldiers". Too late generals, as you're arguing, your soldiers are being wiped out. If you have agree to run, you might make it, your soldiers may be able to escape and still alive. Or if you decide to strike back, even though you don’t have the chance of winning, at least you take down some of their soldiers, not die in vain for nothing in confusion.

See my point now? If they had one absolute leader to follow, the outcome of both stories would have been different. That's why we don't need more than one leader. Oh wait, sorry, that's not the story of the Titanic, I screwed up the story, I didn't intend to make fun of unfortunate tragedy. I'm sorry.

However, one absolute leader is not good either, example, Hitler with his vision of totalitarian, autocratic, single party, national socialist dictatorship. He's absolute, and whatever he said, that would be whatever his followers had to do. No, if he listened to some people, if he had some people that would remind him, it would have been different. Maybe a system like pilot and co-pilot is good. The pilot is the legal commander, and in the event of incapacitation of pilot, the co-pilot will assume the command. Co-pilot will assist pilot to fly the aircraft. If unlikely event happens, the co-pilot might give pilot advice or whatever, but the pilot is the one who decides the final decision.

Oh wait, isn't that what my country has been doing? What an idiot I'm, thinking so long for nothing. -_-" But at least I figured out why (excuse).
