I'll answer the second paragraph first, yes, but that's out of the scope of the OP.
As to the first part I really want to examine how the war would have turned out had the Turks still joined the Central Powers.
However, if their delivery did mean the Ottoman Empire remained neutral in World War One that changes the course of that conflict considerably and it probably changes the history of Turkey and the Middle East beyond recognition. It's possible that there would still be an Ottoman Empire with its 1914 borders. Thus, no State of Israel, no Arab-Israeli conflict, no Saddam Hussein in Iraq and no civil war in Syria, but for all we know the alternative might have been a decades long guerrilla war fought by the Arabs for independence from the Turks that was even bloodier than the OTL history of the Middle East since 1918.
In World War One for the British Empire:
- No attempts to force the Dardanelles and Gallipoli Campaign;
- No Mesopotamia Campaign including the Siege of Kut;
- No Levant Campaign including no Lawrence of Arabia.
For the Entente more generally:
- No Caucasus Front for the Russians;
- Bulgaria probably doesn't join the Central Powers;
- Serbia probably holds out;
- No Salonika Front.
Did I miss anything out?
