Without the Great War the Ottomans should have more opportunity to survive. I feel its biggest threat would be Russian designs on the Straits but we know the other powers are strictly opposed. I can see why folks argue that Britain is sharpening the carving knife but I am dubious. Britain was the biggest creditor to the Ottomans and just before the war had come to terms with German investments, the Iraqi oil was divided in favor of British interests, Britain holds the Ottomans in the noose from Aden to Kuwait but had no love for the Arabian tribes who were just as must a threat to them. Germany had few places to pour money so the OE was its ersatz Empire, so long as they are in the mix I think Britain is happier to exploit things rather than shatter it. Britain holds the Persian oil, the biggest part of Ottoman concessions and will be pressed to develop more. I think Russia is still far more focused on China to go to war for some more Islamic lands, rather I see it meddling in Persia where there is wealth not peasants. And I think we underestimate American interest in oil once Arabia is realized to have huge potential, until then she is the biggest exporter. So the OE will be sized then in the late-1940s or 1950s. But the British and Germans likely have a better working relationship on the ground and would need to fend off the American desire to get a piece of the bonanza. The better threat is rebellion once the Arab tribes realize they sit on the wealth.
The OE will shake off its debt and its dependence, but will it do more than just survive? Overall I think the evolution is longer termed and overall even with massive revenues from oil the OE remains rather hodge-podge in development, the wealth distribution will be almost as unequal as in any sheikdom, the bulk of monies likely skimmed, wasted or overspent on vanity projects or military hardware, discontent might run just as high, so oil wealth is not the panacea but the OE might do far better, that is the potential.
