This is interesting stuff. I'm just wondering: what is known about the intentions of German foreign policy in this era? Of course it's known that Germany was trying to isolate France from 1871 to 1892, but once the Franco-Russian Alliance was already in existence did elements in the German government still consider the break-up of France and Russia a plausible German diplomatic goal? It's beyond doubt that the German government didn't consider it a plausible goal by 1914 and it's probable that they didn't at the time of Nicholas and Wilhelm's aborted attempt at an alliance (though that might have been just that anything touched by Wilhelm II was toxic due to him being so discredited by his own clumsiness even then) but I'm not sure when the transition occurred (presumably at different points for different people in the German government).
The Germans are all over the place at this time. They see an opening to maybe wean Russia from France At the same time, there's the Armenia affair which has to be taken into account.
The British have allowed their foreign policy to be hijacked by "humanitarians" who know nothing of the reality. They've gotten it into their heads that they should actually enforce the Congress of Berlin and give the Armenians some autonomy. For some reason, they convince themselves that the Russians are going to help
This horrifies the continent. Nobody wants to see the Ottoman Empire break up. Austria and Germany see the Sultan as an ally if Russia attacks. France has huge business interests and the Russians not only have an understanding with the Sultan (keep the straits close and we'll leave you alone) but are scared that their own Armenians will get uppity. So everyone agrees to help Turkey.
Now the English don't know this yet because the Russians are pretending to help all the while reassuring the Sultan that there's nothing to worry about.
The Russians actually had asked for England to join the intervention
I wonder what the British do if the Russians do this one. On the one hand, Russian interference in general is regarded with continual mistrust ("Russian diplomacy, as you know, is one long and manifold lie.") but on the other hand it might be considered a positive for Russia to be busy in East Asia and thus the bear's nose kept out of South Asia.
I think they back down. First, Spain, France, Germany and Russia are a very powerful coalition. Might want to pick a better time for a fight
Then there's the little problem that the English had assured the Russians that they wouldn't object if Russia took a port in Korea (that Armenia thing again) and had in fact proposed something along the same lines (Korean independence and Japan to get an indemnity)
Its really going to be awkward to explain to the public that you want to fight the world over the size of an indemnity.
I have never figured what the Russians were thinking here. I could see deciding on an accord with Japan but if your going to push them back, push them all the way back.
You might, if your really clever and lucky, even get a clause stuck in there that Japan can't buy any battleships.
