I don't know where everyone keeps getting this Assyrian ethnic cleansing stuff. Nobody has ever mentioned this until the last few years, and those who advocate it always tie it to getting reparations from Germany for not doing anything about it.
The Assyrians got their own line item in Ottoman censuses, which listed 60,000 of them, and correcting for undercounting (especially of women), there were never more than about 100,000. Their losses were the least of any ethnicity in the war zone, and were what you would expect if a war front moved over your land six or seven times. I've only known one Assyrian personally, and her anger was directed solely at Saddam Hussein - but that was 5 years ago and I'm sure the propaganda machine is busy turning out young Turk-haters as we speak.
In any case, it's ludicrous to take at face value the figure of 1 million killed in the war - that would have made them a bigger minority in the Ottoman Caucasus than the Armenians, and it doesn't seem likely that history could have totally ignored them for all those centuries.
In any case, they have never had a great enough population, either in absolute terms, nor density, nor percentage of population in any area inwhich they lived to form a state.
