History does not do a good job informing people about WWI, at least as it is conventionally taught. Few know the powder keg Europe was then and had been for quite a while. The Spanish American war almost became a world war in the Philippines. And much more. As ArdentAtheist says though, he is correct in that this is a time to remember those who served and did so for the greater good. Not necessarily the best time to argue the reasons behind the multitude of wars. My father served in WWII and few would argue once it started that the many who served, especially for the allies did so to stop some mad men. Yes, in reflection, two other monster dictators stood at the helm of their countries as the war ended: Stalin and Mao. Study that tomorrow; today we need to respect those who served.
