It’s not so surprising that Theodore Roosevelt had a lot of opinions about America’s place in the world. While there was no seizure of the country, Roosevelt was on alert—he wasn’t about to let Europe have any influence on his side of the globe. Tyler Kuliberda: As Americans, we weren't involved directly in the Russo-Japanese War, but I've heard it described as World War Zero; it was an early mechanized war. It took place in 1905, and so I mean it's only about 10 years before the first World War. And so this was another great moment in the history of this country, and a great moment for Theodore Roosevelt.
