First off, one example of isolationism would have to be when the United States declined to give aid to Hungarian patriots in 1849. I chose this example because the U.S., for most of the time, wanted to stick to a policy of isolationism, where they just weren’t involved with other foreign affairs. In this case, the U.S, did not get involved with Hungary because they just didn’t want to be involved with political/foreign affairs. It’s really as simple as that.The reasoning for the U.S. wanting to be isolated is just simply because they didn’t want to put themselves in danger when assisting another country with their own problems. It’s the same as when they didn’t want to get involved with Poland’s movement. The U.S. doesn’t like to cause problems for themselves.A perfect example of intervention would have to be when the United States attempted to mediate the Venezuela-Great Britain dispute in 1895. Tensions were high after gold was found and both countries tried to claim that their country discovered the gold. Things started to settle down once the Monroe Doctrine was introduced/brought up, which basically stated that European countries could not intervene with anything to do with the Western Hemisphere.The reasoning for the U.S, being involved would just have to be to make sure everyone knew that the Monroe Doctrine was set in stone and could be used at any time. Also, the U.S. wanted European countries to know that the Monroe Doctrine would be used if situations got out of hand. The U.S. just wanted to be the mediator and peacemaker in the situation because Venezuela and Great Britain would have probably caused more trouble in other areas.Lastly, one example of imperialism would have to be when the United States annexed Hawaii in 1900. In Hawaii, sugar was the dominant export, meaning that it had a lot of significance for other countries as well. In 1875 a treaty was passed which allowed sugar from Hawaii to be imported to the U.S. without taxes. Since the United States saw this as a benefit for the economy, they pressured the Hawaiian government into allowing them to have a naval base at Pearl Harbor. However, the McKinley Tariff obviously ended the agreement between Hawaii and the U.S because import rates were higher than usual. With that in mind, Hawaii went through an economic depression in which their main export, sugar, wasn’t being sold as much.The reasoning for the U.S being involved in this situation would have to just be for the benefits of the economy. Obviously if there isn’t a tax placed on a good, it’s even easier to be sold. Since sugar was the main product in Hawaii, the U.S. jumped on the opportunity to gain economic value.
