Serbia accepted all parts of the AH ultimatum, except for one, which was a complete violation of sovereignty.
There were no significant negotiations over this, because that ultimatum was not intended to be accepted.
My comment was specific enough, go fuck yourself.
EDIT: Also using tired metaphors like "powder keg" in the context of WWI does the opposite of making your argument stronger. Argumentation is about logic, not about conforming to style. You might also want to lose that smug tone, it's equivalent to spending your opponent's goodwill on something unconnected to the subject. You might call the situation where everybody wants war a "powder keg", yes, but that doesn't really matter, war already was in the air for a few years before the assassination. In newspapers, in diplomacy, in preparations for their own grand victory by all big powers. Since Balkan wars (Ottomans losing trust in British world order), Bosnia and Herzegovina (South Slavs realizing they are food), Russo-Japanese war (ruining Russian friendship with Germany and Austria).
