Why did the United States enter World War I?

Answer by  Kurt (4579)

There were a combination of factors that led up to the US entering WW1. Germany had sunk ships going from America to Britain which killed many American citizens. There was also an offer from Germany to Mexico of southern American states if Mexico declared war on the United States. These were considered sufficient grounds to declare war.

Because we were tricked into it. War is the most profitable industry there is, it was designed to put the US into debt, which it did, and make a few people (bankers) very rich. Whenever you want to know why something is the way it is, just follow the money.

Basically, World War I was largely a British endeavor. The main propaganda outpost of early Britain, the Ministry of Information, pushed heavily to convince the United States to enter. Britain needed the backing of the United States, and they did so by convincing American planners to help drive up a kind of phobic hysteria in the American population for support.
