During the conflict between nationalists and states' rights advocates, the idea of nullification developed. what was the central principle of nullification?

The central point of nullification was for the state union to vote and have a right to deem an unconditional law and vet it.

Explanation:

The nullification principle was based on the given theory that stated that the state could nullify, invalidate the federal laws that were not constitutional. However, people taught that there should be tools that be put in place to ensure there are no risks of passing laws that are not constitutional. Ultimately the state kept the powers to determine if the federal government exceeded the capabilities of declaring an act void and of no use in the jurisdictions.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.

i think the answer is: cuba wanted to be independent from spain, and the u.s. wanted to end spanish rule in the west.
