There was westward expansion from 1900 onward in the American territory that started with Louisiana purchase.
<u>Explanation:</u>
Americans upheld the possibility of abroad extension in the late 1800's on the grounds that they needed to extend exchange and trade to Latin America, to spread majority rules system, to politically impact different nations, and grow so America has a more area.
These were the reasons why America wanted to expand it's territories and expansion of the country in the late eighteenth century more over the Louisiana purchase led to the expansion of the country. The U.S. expanded its territory largely through military conquest. Even purchases from other European powers, such as the Louisiana Purchase and Alaska.
The USA didn't want to export oil to Cuba, so instead of using the US's oil they started using crude oill from the Soviet Union, American companies in Cuba than started to refuse to refine the Soviet's oil. Then Cuba nationalized American-owned oil refineries in Cuba as a response to what was going on.
