While we have to be very critical about the role of A-H in the leadup to WWI, it's not like they planned or even accepted the possibility of an all-out European war, unlike Hitler who sooner or later was going to envelop all of Europe (maybe except the UK who he would have liked to be his partner, at least for a time). Also, the roles of the Germans, Serbs, Russians and to some extent even French need to be critically analysed too in the case of WWI, while in WWII, you can squarely lay the blame at Germany's feet for the outbreak of the war.
