Oxford historian Niall Ferguson talks about the real motives for war. His book, "The Pity of War" concludes that World War I was unnecessary.
In the US, World War I led DIRECTLY to:
- The IRS and the taxing of personal income (there had never been a tax on personal income in the US before)
- The Federal Reserve (The third attempt to create a central bank in the US and the first attempt in the 20th century)
- The Pentagon and the explosive expenses of a 'standing army'
- The draft (the second one in US history, the first being the Civil War)
- The invention of modern propaganda.
In Europe, the slaughter during World War I was unprecedented making the extreme excesses and violence of the 1930s and the Second World War possible.
