So our choices were, all the hundred million plus who died as a result of the history we have now, with a European Union effectively dominated by Germany.
Or Germany winning World War I, none of the subsequent hundred plus million dead, and a Europe effectively dominated by Germany.

In 1917, nobody could have predicted the Depression, the rise of Hitler, and WWII. A German military victory in 1917-18 seemed like a terrible thing, and it would have been.
