Why was president Polk willing to go to war with Mexico

to further the idea of Manifest Destiny

Explanation:

Manifest Destiny was simply the belief that God has destined the U.S., especially the white Anglo-Saxon race within the U.S., to expand to and rule the North American continent.

This term was used in the the 1840s, especially by James Knox Polk who was the 11th president of the U.S. between 1845 and 1849, as a justification for the war with Mexico.

this isn't a question and if you're going to list things be kind and use commas.

the first 10 amendments to the u.s. constitution are known as the bill of rights. those 10 amendments establish the most basic freedoms for americans including the rights to worship how they want, speak how they want, and assembly and peaceably protest their government how they want. the amendments have also been subject to much interpretation since their adoption, particularly the right to carry a gun under the second amendment.

"a bill of rights is what the people are entitled to against every government on earth, general or particular, and what no just government should refuse, or rest on inference," said thomas jefferson, the author of the declaration of independence and the third president of the united states.
