Thanks. I haven' t seen the film myself, but I guess " illusion" is the word that can describe the situation in the Republic. By that time, the Republic itself was a false utopia. At the first look, we see that it looks like a place much better than our world. The politicians like Amidala and her decoy( I know, Sabe isn' t actually a politician, and she mostly does Padme' s biddings, but still, she temporarily pretended to be a Queen) really care about their people, there is democracy and everyone is used to doing everything in a civilized manner. Most people, including Amidala, minus Qui - Gon Jinn in some situations, act as if they lived in a paradise located in the physical world most of their life.But it is also an illusion most of the people in the Republic have. Amidala and her Council are people who really suffer for their planet, but still, they are naive due to this illusion they grown up seeing, and really Amidala is one of the few leaders who has such devotion. She( here I mean the decoy) realises it when she arrives on Coruscant, seeing how really corrupt everyone is. And when she sees that really there is no hope, she takes a risk to make a stand, because she has nothing left to lose. The Senate won' t help her in time, so she decides to form an alliance with the Gungans, in which they will stand together for their planet. There is no other way, so she should try the last one, even though the odds are very little. But I guess it' s off topic.
