However, not all Americans or their political leaders believed that the United States was a divinely favored nation, or thought that it ought to expand. For example, many Whigs opposed territorial expansion based on the Democratic claim that the United States was destined to serve as a virtuous example to the rest of the world, and also had a divine obligation to spread its superordinate political system and a way of life throughout North American continent. Many in the Whig party "were fearful of spreading out too widely", and they "adhered to the concentration of national authority in a limited area".  In July 1848, Alexander Stephens denounced President Polk's expansionist interpretation of America's future as "mendacious". 
To conclude the United States was unjust in its declaration of war on Mexico in 1846. The US was clouded with dreams of Manifest Destiny. It had a president that was obsessed with fulfilling campaign promises and greed for new land. Also Polk was looking for revenge for the denial of the proposal for buying California as was evident in his original reasons for declaring war on Mexico. Also the US provoked this boarder dispute into the two-year war that it became by purposely inciting the Mexicans into a fight. All these reasons are the evidence that the US was not justified in declaring war on Mexico.
Beginning in 1826, Georgian officials asked the federal government to negotiate with the Cherokee to secure lucrative lands. The Adams’ administration resisted the state’s request, but harassment from local settlers against the Cherokee forced the Adams and then Jackson administrations to begin serious negotiations with the Cherokees. Georgia grew impatient with the process of negotiation and abolished existing state agreements with the Cherokee that had guaranteed rights of movement and jurisdiction of tribal law. Andrew Jackson penned a letter soon after taking office that encouraged the Cherokee, among others, to voluntarily relocate to the West. The discovery of gold in Georgia in the fall of 1829 further antagonized the situation.
