Just a few links for Armistice Day, or Veterans’ Day if you prefer:

World War I seems like it’s part of the distant past, but it’s worth studying it is the classic example of events taking on a life of their own. That should serve as a warning to us today. As threats are made, plans are laid, and pieces are put into place in our ongoing spat with Iran, war becomes more likely. Eventually, if we’re not careful, that war will begin because one side or the other goes one step too far, and events dictate a response that ends in hundreds of thousands or even millions of deaths. It hardly matters whether most people on both sides don’t even want a war. We’ve seen it happen before, and it can easily happen again.
