Amy Chua believes that for a country to become a world dominant force, the country must be tolerant. A country that is tolerant isn't promised a path to world dominance, but tolerance is a required characteristic for a world dominant force. Tolerance does not mean that all races are treated equally but that the races can coexist together and work to make their nation better. Intolerant acts such as ethnic cleansing prohibit a country to become a global dominating force due to the fact that acts such as ethnic cleansing are inefficient and require too much work, work that could be put to better use and could possibly benefit the country and push it closer to world dominance. What some people may consider tolerant may not be the same for others, due to the fact that tolerant is a relative term, so Amy Chua claims that in order for a country to be considered tolerant, it must be more tolerant that any of its current rivals. For a country to be a world dominant force it must meet three conditions: The power that the country beholds must clearly surpass the power of its rivals. It must not be clearly inferior to any other power in the world, neither economically or in military strength. Finally, the country must power over a considerably large part of the world.
The Achaemenid Empire is the first nation that Amy Chua describes, she notes that this empire practically has no written history and almost all information comes from oral testimonies, which can be easily tampered with or exaggerate and this causes the origin of Cyrus the Great to be enveloped in legends. Cyrus' grandfather ordered to have his grandson killed in order to ensure his place at the throne. Cyrus survived and later confronted his grandfather to take over the Achaemenid empire. When Cyrus was taking over the empire he did not slay the heads of the each kingdom's ruler but replaced him. He did not interfere much with the ordinary people
