TR's Foreign Policy George F. Kennan and Walter La Feber are two historians who take very different views of United States foreign policy in the late 1890s. Thesis Kennan's main point is that the United States went to war with Spain because of impulsive decisions made based on public opinion. This public opinion was created thanks to the press. At that time the press was known as the Yellow Press. This type of journalism is similar to today's National Inquirer. According to Kennan, the yellow press whipped the public into a frenzy and caused the government to make an impulsive decision for war. However, La Feber's thesis states that when the United States entered the war, it was deliberate. La Feber believes that the need for trade was at the heart of the idea of ​​expansion that led to the war. Kennan simply believes that the United States entered the war by mistake, while La Feber believes that it was deliberate. ​​The three main things Theodore Roosevelt did during his presidency regarding United States foreign policy were the corollary to the Monroe Doctrine, the acquisition to the Panama Canal Zone, and the dispatch of the Great White Fleet. The corollary of the Monroe Doctrine is the idea that only the United States could become involved with other countries in the Western Hemisphere. The government did not want European countries to interfere in the affairs of North and South American countries. TR was able to access a plot of land in northern Colombia, now known as Panama, that was abandoned by a European canal company. With this land, the government financed the continuation of the work. Roosevelt sent the Great White Fleet around the world to show other countries that the United States had a good navy. TR's foreign policy was essentially divided into three segments. TR's foreign policy could not accommodate either Kennan's or La Feber's thesis. However, it looks more like La Feber's than Kennan's. Kennan believed that United States foreign policy was conducted impulsively or accidentally. But as with La Feber's thesis, there is certainly a reason why Roosevelt did what he did regarding U.S. foreign policy. Unlike McKinley's commercial reason, Roosevelt acted according to the idea of ​​power..
