Answer:
Manifest Destiny was an expansionist political stance carried out in the United States during the 1800s, through which the nation's expansion from the Atlantic Ocean to the Pacific was urged. Thus, it was sought that the United States became a bioceanic nation, controlling trade on both sides of the continent.
Therefore, Manifest Destiny could have equally been fulfilled without annexing Texas, since this state does not border either ocean but the Gulf of Mexico.
