With military strength and international affairs being basically non existent, Americans could afford to live in their own bubble. However, due to events such as the sinking of the Lucitania and the Zimmerman note, this enjoyable and comfortable style of living was left behind and militarization was on the rise. Though militarization is only a single word, it encompasses many different components. The first part of militarization was acceptance of America as a world power. This acceptance did not only apply to the United States accepting itself as a world power, but having other dominant countries accept this fact as well. If the U.S. wanted to be viewed by other countries as a world power, then those living in the U.S. had to start considering themselves as a powerful player in the game as well. The second aspect counterbalances the first one to a certain extent; America had to accept the fact that it was indeed vulnerable; vulnerable to attack, threats, possible defeat, etc. Thirdly, America had to fully reject its prior belief in isolationism. Militarization was indeed gradual process, but, the first step in letting in the new idea was letting go of the old one. In one of his many speeches to the public about the need for military build-up, Roosevelt stated, "you have to start to look at the world as harsh realism". Roosevelt, one of the biggest advocates for militarization tried his best to point the people in a certain direction. He wanted it to be known to the public that national security is at the heart of militarization. Roosevelt's quote allows transition to another piece of militarization, the need for an all power military component to society. The last two parts of militarization go hand in hand with one another. It called for American citizens to act a certain way, to be role models, and to support the "new" patriotic ways. Serving your nation militarily (either by fighting on the fronts of aiding in the war effort at home) was now the highest form of patriotism possible.
