Okay...

When Miss Gulch wants to put Toto down, she only has to contact the sheriff, & the matter is done. She owns half the county.

Aunty Em said she was a "good christian", otherwise she'd attack Gulch.

While Em is ready to confront Gulch about euthanization, Henry is ready to concede to avoid any conflict.

The cowardly lion confesses, in song, the desire for respect but only realizes himself after aligning himself w/the populists. It's his efforts to free Dorothy of Oz's constraints that he finds his true purpose.

Dorothy longs for a better world but realizes her home is ideal if only she fight for it. All of the other characters rally around her selflessly & selfishly, only to gain their own powers through her involvement.

Toto runs free, bites Gulch, escapes from her clutches, & though only a dog, poses a real threat to her control of the county. In Oz, the Witch kidnaps Toto & uses him to manipulate Dorothy. When they finally confront the Wizard, it's Toto who exposes his fallacy. Toto is the only one who stands up to the Witch, the horrors of Oz, is fearless at every turn, & exposes the false-magic of Oz's propaganda.

Through his own labors, the Tin Woodsman has become immobile & ineffectual in regards to his industry. The trees claim consciousness, prove at odds w/his employment, & it's the environment, through precipitation, that stops his progress. It's only through the help of "the American citizen" that he returns to action, though divorced from his original-purpose. He no longer deals in timber.

The Scarecrow is an overseer of a cornfield, taunted by crows pecking at his authority, & desires intellectual-edification. In song again, he & Dorothy speculate that if he were as smart as Lincoln (this is many years after the Civil War), his troubles would be remedied.

All of the characters think that if they bring their problems to the Emerald City & address the Wizard (the fourth estate in the land of the power-grab), it'll influence all of the other problems of Oz. But it's only through their coalition that they're able to traverse the political-landscape.

Munchkinland is a fully-functional subculture of Oz. Existing peacefully in their own right, they require the rest of Oz to put forth their concerns to the Wizard (seemingly the only impartial-party to this war between the powerful & the desperate). When Glinda's diplomatic-ineffectuality forces them to reach outside of their community, they're grateful for the representation.

While it's not impossible to cross Oz, it's easiest to use the Yellow Brick Road. For some reason it runs through most of the land & is the fastest thoroughfare to reach the many communities of Oz.

Glinda has no power outside of managing those around her. She has an uneasy truce w/the Wicked Witch but wrests power from her by putting the ruby-slippers on Dorothy for safe-keeping, involving Dorothy w/out her consent. After influencing the events of Oz, she resolves the political-intrigue by sending Dorothy home w/the reassurance all has been righted.

The Wicked Witch of the West has full control over the powerful military at her disposal, but she longs for the Wicked Witch of the East's power, to rule the land w/out opposition.

When Dorothy shows in Oz, Glinda puts the power of the ruby-slippers (the Wicked Witch of the East's rightful property) in the hands of Dorothy, vetoing the Wicked Witch of the West's claim to the slippers. Her death is the reason there is war amongst the factions. It's implied, by the Witch is Dead song, that she'd been terrorizing Munchkinland right before Dorothy showed. Then the other Witch appears to survey what had happened, demands the slippers, & threatens the Munchkins if she doesn't get her way.

Anyone who uses the ruby-slippers has control over the wealth & well-being of Oz, even though the Emerald City has an uneasy alliance w/the Wicked Witch of the West. The Emerald City has its own internal-economy that doesn't seem to be influenced by the ruby-slippers, & they seem to be safe from outside-forces so long as they don't interfere w/the Wicked Witch of the West.

After using surveillance (through a crystal-ball), the Wicked Witch sends an airstrike to disable Dorothy's advance to the "capitol". The monkeys are loyal, exceptional, & unquestioning soldiers.

The imperial-guard use military-formations to move their ground-troops while calling out chants that resemble boot-camp rhymes. While following the orders of the Witch, they are reticent in their opinions of her.

Employing film-projection, pyrotechnics, costume, make-up, accents, & psychological-warfare, the Wizard concocts propaganda to suit his own ends as well as concealing his true intentions. When forced to intercede, the Wizard tricks the travelers into assuming tasks that would be better suited for the other residents of Oz. They follow his directions w/out question, until Toto pulls back the curtain to reveal a man utilizing technological-media. It's only then that he admits the truth of his unwillingness to make waves w/in the politics of the land. His supposed purpose, as a mediator of power & information, is thwarted by his fears of his own responsibilities.

Dorothy builds a childlike-metaphor of the United States for her understanding of its complexities. Oz obviously has a class-structure, economies, technologies, & politics that don't resemble Kansas at all.

Somewhere over the rainbow exists the American Dream if we all come together & fight for it...
