PLEASE HELP!!!"And that claim is by the right of our manifest destiny to overspread and to possess the whole of the continent which Providence has given us for the development of the great experiment of liberty and federated self-government entrusted to us." --John L. O'Sullivan, New York Morning News, 1845.

B) America needed to seize territory to prevent future conflicts with foreign powers. C) it would help lessen the tensions between white settlers and the Native Americans.

Answer 1

O'Sullivan argued that American expansion and imperialism was justified because A) gaining new territory would allow democracy to spread throughout the continent.
He says in the quote that "Providence has given us for the development of the great experiment of liberty and federated self-government entrusted to us," so you can see they wanted to spread their ideologies throughout the country. 

Answer 2

O Sullivan argued that American expansion and imperialism was justified because he believed that gaining new territory would allow democracy to spread throughout the continent.  

Further Explanation:

He disapproved of the involvement on the part of the United States in the Mexican American warwar though eventually he came around to harbouring the view that the result would certainly be fruitful to both the countries. In the later years, he was of the opinion that the fate of Mexico was to perish while that of the United States was to prevail and dominate the arena.  

The concept of Manifest Destiny is often credited to him but it must be noted that he not the originator but definitely one of the most vigorous advocate of the concept; a concept which was reflection of his faith in the invincibility of the hegemonic power- U. S. Though the concept was often a subject of ridicule by the Democrats during the initial phase, they came around to accepting it as well.
