According to the book I'm reading (Palestine: A Personal History by Karl Sabbagh), the King-Crane Commission, which reported in favor of self-determination for the Palestinian Arabs, failed to be received due to Wilson's stroke. It ended up being released some time later, after the Paris Peace Conference was all over with (1922, actually).
So...what if Wilson never suffered a stroke, and/or the report was finished up a bit quicker (a question the author poses in the book)? What might be the effects of the report?
