Not really. Global Scale Wars were a unique thing back then. The Great War, the war to end all wars, was thought (hoped!) to be the only one of its kind. They had a lot of conflicts between major powers, but at least for the west, 17 million deaths excluding the spanish flu epidemic was a massive outlier.

Even the Mexican Revolution, listed on Wikipedia with an upper estimate of 3.5 million, wasn't a quarter of that, and it wasn't global. The last thing in the west that came (somewhat) close was the Napoleonic Wars with an upper estimate of 7 million, a hundred years earlier. China has had several massive death counts in various wars and rebellions, but that won't have been very present to the average western civilian.

WW1 brought with it a slew of new developments in military technology and capability for destruction. For the world to have not just one, but potentially two conflicts considered at least on par with The Great War would be very concerning.
