where?
I was being mysterious...
Some thoughts on this specific question,
I think the major problen with post-Balkan war scenario is the Enver Pasha is in power. Any Empire with Enver at the helm has done some pretty horrendous things and turned to rigid Turkish nationalism. This will doom the Empire over the next decade.
Britain will have its own problems. Ireland, India, war debt, and radicals of all stripes will keep Britain busy with a late victory. But a neutral Ottoman Empire is a natural ally to help contain Russia (much like Japan).
Germany was not as tied at the hip until late in the Great War game. While the Bagdhad Railroad was a German interest, it was privately funded and was a private company. Its not as if the German government will be sending garrisons to Basra.
The Arab revolt was manufactured. Prior to the war even the most radical arab politicians only called for autonomy. When Arab expats in Paris called for independence there was widespread disagreement at home. Most Arab leaders felt that remaining whole was a better alternative to European domination and the loss of Libya only reinforced those feelings.
Most of the Ottomans christians were in Rumelia and were lost. Any OE that commits atrocities against its Christian citizens will be met with world wide condemnation. Germany specifically would not stand back and ignore it.
But on the flip side if Enver is in power he may just become this worlds Hitler.
In terms of Japan, as a country that did industrialize and "westernize" its forces, could simply remain underdeveloped. It could be colonized and suffer the same outcome of any number of post colonial nations.
