My advice to the Sioux is to put on the War Paint, leave the reservation, and take your bows and arrows and horses to France. Ten drunken Sioux on horseback armed with bows and arrows can take Paris in about two hours. Then you can raid the Crazy Horse, scalp all of the American Tourists, grab the nekkid French Dancers and take them back to the reservation. Then, and only then, will people stop messing with the Sioux and other proud Native Americans.
One thing I almost forgot -- Sioux, you'll need to "scalp" the French Dancers also, albeit not on their heads.
first they have to stop the lap dances then "scalp 'em"
