If the CP victory is after a long war, it is likely the Turks will have to grant some concessions to the Arabs, perhaps an Arab kingdom or two (Damascus/Hejaz?)
Assuming the most severely oppressed Jewish populations are in newly created Poland, Ukraine, Belarus, as well as civil-war torn Russia, and generally poor, there is likely to be increased repression during national development in those new countries and equally likely refugees from that repression moving west into Germany, Austria, Hungary, Romania, etc. (or Austria-Hungary -- I'm not convinced the dual monarchy stays together, even in a CP victory)
If that occurs, the great powers with pressure from the Zionist movement, may privately or carefully publicly suggest and encourage the Turks allow a semi-autonomous Jewish state within a state, as a potential counterbalance to the Arab state or states within a state. This ameliorates the refugee problem in Europe. I do not know if this compromise would be acceptable to anyone though or how plausible.
