Actually fair enough no official treaty but pretty damn clear mutual agreement and support, (the Russians had just basically put Pasic back in government). the Russian had not been shy about their backing either, and the AH were well aware of it. Russia had been in with Serbia since 1807, and had basically been making moves in this area since then. AH knew they were countering Russian influence in the area (and vice versa of course).
Actually Russia was traditionally Bulgaria's sponsor on the Balkans and not Serbia's. Serbia has been practically and especially economically a dependance of Austria till the tariff war of 1906-08. Austria and Russia had various agreements to this effect during the century. Serbia becoming Russia's main protege on the Balkan was a pretty new development meaning the Balkan wars.
Well yes, but high ranking Serbian officials cover a lot of ground especially as Serbia had it's own factionalism going (which is why Pasic had needed Russian support). Also when you are multi ethnic empire guess what you will be susceptible to people looking at separatism, how you deal with depends on you
I have to agree however seeing as before WWI likely only active russian support for Pasic saved him from being violently removed from power by military officers who were involved and part of the Black hand and seeing how this same military had a free hand in Macedonia i think im justified to say that Serbia was basically a terrorist state. Maybe given a lot of time Pasic might have reigned in the military but im doubtful of that.
Also separatism is one thing - far from a friendly step on itself but still. Planning and performing acts of terrorism is another.
Did he? More importantly did he condone it? Pasic wanted peace (not because he was a lovely peaceful chap who loved AH, but because they were still skint from the last Balkan war), dont get me wrong I've no doubt there was a line between some Serbian factions - Black hand - Young Bosnians. But this idea that the assassination of FF was some official foreign policy move by the Serbian Gov while it might make AH look better, isn't necessarily true
He did know about it and also issued a warning to Vienna - though in such a vague way that it proved useless. The point I was trying to make was that even though he knew about it he was powerless to stop it - that shows both the support the Black hand enjoyed in Serbia and the balance of power within the state.
This might also look like im trying to make AH look better. I dont - AH wasnt a nice place, activly wanted war with Serbia, however he had good reason to want to war with Serbia.
It could have acted faster and handed the world a fait accompli that no one was going to go to war over (but fucked that option up)
It could have framed it's ultimatum demands in such a way that they could have be met and satisfaction given/extracted, and not be about the most transparent looking for rejection excuse for war ever (the Serbs actually agreed all but one demand, but no that's not good enough no choice but war!)
it could have agreed to international arbitration (but didn't like that idea thinking it wouldn't get a free hand). This was the big one for me there were international attempts to do this right up until the eleventh hour but both AH and Germany said no, why say no when general war is looming?
It had options, it's not like it was forced to do what it did, especially as since it was relying on the German blank cheque and what that could mean for escalation.
Austria did mishandle the situation however I dont think they could have done anything to persuade Russia not to back Serbia. Looking at the realities of AH military creating a fait accomply you propose was impossible.
An international arbitration has the problem of who should be the judge? Russia has rejected the results of Austrian investigation before they were finished based on the fact that a decade earlier austrian authorities did try to condemn a sebian nationalist on fabricated evidence - and failed by the way. Paris and London accepted the Russian position.
Seeing how intervovene were official and unofficial Serbia before WWI i highly doubt any intervention sort of a long military occupation was going to solve the situation. Unless you propose that Austria should have given up all of his south slavic territories without a fight.
