I finally watched All Quiet On The Western Front which was brutal and fantastic but it strikes me that I don’t know as much as I would like about this conflict.
What are some good sources for analysis and historical perspectives?
Edit: thank you all for your recommendations and perspectives 
Christopher Clark’s The Sleepwalkers: How Europe Went to War in 1914 is pretty good, one of the books historians usually recommend
I added this to my book list. Thank you
