Suppose the Ottomans remained neutral in WW1 and conquered Arabia. The Unionist faction of the CUP, the party that was dominant during WW1 IOTL, rises to power and imposes their views of:
1) Social Darwinist competition between the weak and democratic West (UK, France) and the determined , autocratic non-West (Germany, Turkey, Japan)
2)The need to gain ethnically Turkish land in Central Asia and the Caucasus
3)Using jihad to motivate soldiers to fight for the Sultan like how Japan used bushido rhetoric
4) Industrial modernization, again like Imperial Japan
5)Traditional gender roles were to be enforced, although women were recruited to work for the war effort IOTL
on the country, banning the Socialist Party (as they did IOTL) and imposing quasi-fascism. If they declare war on Russia and Britain, countries which possess territories they want either as colonies or puppets, how easily could they be defeated?
