Hey, this question is most likely going to be deleted for being a 'what if' question and this sub doesn't allow that. However, if/when you resubmit, this is actually a great question if it were worded just a bit differently. Perhaps something to the effect of "How much did the First World War lead to the Ottomans collapse?" or even more directly to your question "Did the First World War cause the Ottoman collapse, or did X, Y, Z make it inevitable?"

Sorry, but your submission has been removed because we don't allow hypothetical questions. If possible, please feel free to rephrase the question so that it does not call for such speculation, and resubmit Otherwise, this sort of thing is better suited for /r/historywhatif.
