Germany and Japan favored military solutions more than the United States did. I think the militaristic nations felt they had more to prove on the world stage. For Germans, rearmament became a point of national pride. For the Japanese, imperialism played a similar role. By contrast, Americans entered World War I reluctantly, and they remained reluctant to enter World War II until the bombing of Pearl Harbor left them with few alternatives.
The correct answer to this open question is the following.
Some countries chose military solutions when they faced great depression. That was the case in Germany. The Germans faced terrible economic conditions. People were angry and tired of the situation and elected fascist politicians to run the country. That is how the Nazi Party and Adolph Hitler came to power and believed in the militarization of the country to the degree to start World War II. Italy, with Benito Mussolini at the front, is another example.
Other countries such as the United States, approached the situation differently, as was the case of President Franklin D. Roosevelt who created a series of programs called "New Deal" to face the situation and help the US citizens that were suffering due to the economic situation of the country.
