Pretty remarkable, and it's based upon an actual event.
What the ad forgot to mention was that World War I was such a huge waste (more so than most wars) and could have been avoided (like most wars, I suppose). It also indicates who bears the brunt of such folly, and it's not the national leaders. I recall my father, a historian born just a few months before World War I began, describing the events leading up to the start of the war and the miscalculations and stupidity of the European leaders. There was anger in his words.
