Rebelling for a reason

Through out history, people have rebelled against their leaders for different reasons. In the last 5 years i have heard about some type of rebellion or revolution in different countries around the world. Right now, the revolution in Egypt is the one that has been most know to people around the world and The United States mainly.
The main connection that i see between what is happening in Egypt and what happened in George Orwell's Animal Farm is that here is only one kind of leader. In Egypt Mubarak has been the leader of the country more than anyone else ever has. He cheats to be the leader over and over and to never be removed out of power. That is not necessarily what happened in Animal Farm but i think that the same idea can be built. Animal Farm had different leaders, but the thing was that they were all pigs and it was never a horse or a donkey, or any other animal that formed part of the farm. I think that having one leader  for a really long time is almost the same as having different leaders that can or could be the same. Even though Major might not have been like Napoleon it was still unfair to have alike leaders having the control. I think that in Animal Farm it was an injustice just to let the pigs be leaders. It would be the same as if a man just like Mubarak became leader after Mubarak and after that man another one like him.
In other cases such as what happened in Honduras in the summer of 2009 also connect to Animal Farm. In Honduras, the ex-president Manuel Zelaya tried changing the constitution of the country so that he could do the same Mubarak did and be reelected  every time. He also took advantage of his power treating the people of the country unfairly. In animal farm, Napoleon and the pigs kept changing the constitution in their favor and also took advantage of their power by making all the animals work so they did not have to do anything.
Changing the rules is unfair, and when someone changes the rules against the people, the people respond by rebelling so that their voices are heard.
