Manifest Destiny was less of a well-thought-out strategy and more of a rallying cry or a core conviction. Even though many US officials viewed it as immoral or antithetical to what the US stood for, it permeated the leadership's beliefs for decades. (In other words, even the most "liberal" minded people harbored the notion of white, Christian, American dominance, despite the fact that many others detested it or thought the name was inappropriate.) Both an embodiment of that notion and a planned political ploy, the Louisiana Purchase was opposed by many Americans. Nevertheless, Thomas Jefferson did support the notion of gentile white landowners "lifting up" the unruly, wild continent and creating an agrarian society. He saw "gentleman farming" as one of the most honorable occupations, and he used it to buy land for American immigrants as well as to keep Louisiana out of the hands of the British or Spanish (albeit interestingly, it was purchased through a British bank). What does that imply about the objective? It implies that Manifest Destiny's objective wasn't truly something that was fixed in stone. Before the Louisiana Purchase, John Adams saw a US that crossed continents. Some imperialists imagined a scenario in which the United States controlled all of the Americas or just North America. It merely implies that the US was mostly hypocritical (as nations have a tendency to be) in pursuing a goal at the expense of individuals it trampled on, depending on the lofty aspirations of the person. (I say this as an American who is pleased with how history turned out but who is also aware of people who were injured by it.)
They were all afraid of irritating people (who vote). Since people (who vote) decided their unavoidable future, they didn't want to take any strong stances on anything and just went with the flow and played the tune that the people wanted to hear. They needed to stay in power and not lose it for taking a serious stance.........
Because they did not obey the voice of the LORD their God but transgressed his covenant, even all that Moses the servant of the LORD commanded. They neither listened nor obeyed. (I think that will be the answer to your question)
