I'm reading a Historical Novel about World War One... a subject I know very little about. "To The Last Man" by Jeff Shaara...

One thing I DO know about WW1 is that the US Government started "The Draft" in order to get Americans to participate... At that time, most people worked on Family Farms and Teenage Men were needed to survive as a farm family... Most people had no interest in what was happening in Europe... and certainly, no way were they going to have their Men dying for no reason... So the US Government FORCED Men into the Army... with The Draft... and we drafted Soldiers all the way up until the end of the Vietnam War... 

WW1 had an effect in Russia as the Successful Revolution happened right after the end of the war...1917... 

I just saw the Movie about the 1905 Revolution that did not succeed... Battleship Potemkin... with Abstract Russian music and the Staircase Mass Murder in Odessa... Classic Silent Film...

https://en.wikipedia.org/wiki/Battleship_Potemkin  Three symphonies from Dmitri Shostakovich have been used, with No. 5, beginning and ending the film, being the most prominent. and this is some REALLY BIZARRE MUSIC... Like Frank Zappa...
