The correct answer to this open question is the following.
My informative front-page article will be this.
Title:
"The Moment Has Come. No more offenses."
We had to endure many things. But no more.
It is time, and we trust President Woodrow Wilson. In these difficult times of sorrow and world instability, the United States had to make a decision. And President Wilson was the man to make it right. The United States has entered World War 1.
The Allies so much needed to hear this news. From now on, all the strength and intelligence of the United States are part of the Allied Forces in Europe.
Finally, what events and circumstances influenced US leaders to go to war?
Well, basically two. First, the interception of Zimmerman's telegram in which the German's asked Mexico for its support in the war, in exchange for further support to take some of its territories back from the US. Secondly, the sinking of the Lusitania ship in European waters by the German Navy.
That is why, we, as US citizens, have the moral obligation to support our troops.
