We will break our promise to the US and keep attacking their passenger ships.

Unrestricted submarine warfare

Oh no We have to act fast!

we have to arm our ships from any possible attacks from the German.

and also lets demand them to an end to the German attacks against the unarmed ships

Second reason is the Zimmerman Telegram

We are going to petition Mexico to join us against the US in the war.

We agree because they offered financial aid to us.

We can't let them keep doing this!

We have to immediately urge entrance in the war

The Sinking of American Merchant Ships

We must target the neutral shipping in a designated war zone.

Five of our merchant ships were taken down by the Germans! We need to act!

The Assassination of Archduke Franz Ferdinand

If you do this war will result!

Sorry Archduke, that's a risk I'm willing to take.

The Archduke has been assassinated! Tell the soldiers we are going to war!

Looks like war is on the horizon...
