El objetivo fundamental de Estados Unidos es la neocolonización o neodominación de América latina y el Caribe con el uso de diversas estrategias doctrinarias, filosóficas, políticas, sociales, culturales y básicamente militares: El expansionismo yanqui se origina en la filosofía, doctrina o idea del Destino Manifiesto presentida por los colonizadores puritanos, pues uno de ellos escribió: "Ninguna nación tiene el derecho de expulsar a otra, si no es por un designio especial del cielo como el que tuvieron los israelitas, a menos que los nativos obraran injustamente con ella. En este caso tendrán derecho a entablar, legalmente, una guerra con ellos así como a someterlos.

<em>Declining political participation as a result of the Enlightenment</em> is wrong because democracy was broadened in early 1800, till then only Kentucky and Tennessee could elect and only white men and wealthy could vote, around 1820 eight states were participating in elections and other groups as free-men could vote, later with the ratification of the U.S. Constitution and the 15th Amendment African-Americans and women were also allowed to vote.
This answer is wrong<em> Significant increase in protections for American Indians through new treaties</em>. Around this period many American Indians went to war to protect their land from the white invasions and expansion, many Indians were killed by the whites. Even there were around 368 treats between US government and American Indians from 1776-1886 most of the treaties were about land, but these treaties required the Indians to cede their lands, others to give an annuity for the territory loss, by the time Indians could not purchase American lands so the treaties did not protect the Indians.
The option <em>Rapid decline of political factions in light of an improving economy</em> is wrong because around 1829-1850 there was great grown with the Market Revolution, the improving of economy was not declined.
