Answer 1

Hello there.

Which was a major argument in favor of the Mexican War in 1846? 

Americans who believed in Manifest Destiny wanted to spread the American way of life.

Answer 2

The Mexican-American War, fought between the United States (US) and Mexico from 1846 to 1848, contributed to America's "manifest destiny" of expanding its territory across the entire North American continent.

The major argument in favor of the Mexican War in 1846:

• Option D is the correct answer because the Mexican government was enraged by the United States' annexation of Texas.
• The Mexican government never accepted or recognized Texas as an independent state, believing that the US had no authority to take or annex Texas.
• The United States and Mexico's border tensions intensified in 1946, resulting in the War.

Therefore, Manifest Destiny supporters intended to expand the American way of life across the globe is the major notion of the Mexican war.
