Discuss the extent to which the Mexico American war was what American wanted

The Mexico-United States war was the result of the planned invasion by the USA into Mexican territory to be able to expand the territory in the south and west. The end of the war was given by the signing of a treaty known as the Treaty of Cahuenga. This document was drafted in its entirety by the United States and granted this country control over Texas, the disputed territory between Mexico and Texas that included all the land north of the Rio Grande and the territories known as Alta California and Santa Fe de Nuevo Mexico, appropriating what are now the states of Arizona, California, Nevada, Utah, New Mexico and parts of Colorado, Wyoming, Kansas and Oklahoma (what is known as Mexican Assignment). For Mexico it meant the loss of more than 2,100,000 km² (more than 800,000 square miles) of land, 55% of its territory at that time. In return, the United States would give him 3 payments and $ 15,100,000 as war expenses and cover the damages suffered by his nationals in Mexico.
