Why did the US enter WW1? (At least five reasons, please)

1) Telegram from Germany telling Mexico to invade the US

2) Sinkings of US civilian ships (mainly the Lithuania)

3) Attrocites in Belgium

4) Business and to maybe lift the US out of depression by giving jobs to fight in the war

5) War Crimes that german commited

The Lusitania in 1907. Events in Belgium were used for propaganda throughout the war. The encrypted Zimmermann Telegram. Also because of something about Submarine attackers in Germany. I believe another reason was because they stole Merchant ships.

Explanation: Most of the reasons US went into WW1 is because they didn't go further into it and searched reasons why Germany did this, they went head first into battle -_- Dissapointing how we don't know very much of that

you should try adrenaline. it kicks in in situations like this.
