Cheney Admits that He Lied about 9/11

Iraq: Shias and Sunnis share the same race, language, culture, religion, live in the same neighborhhoods and intermarry regularly.

Wow...just wow.
I think that deserves a

Can you just run off a quick list of the ethnicities and languages of Iraq, maybe give a brief history of the religious conflicts between these "same" religions you speak of.
Maybe touch on the Kurd/Turkoman/Assyrian problems then add in the arab problems with those communities too, possibly deal with the aftermath and consequences of Uncle saddams arabification program, then for good measure mix in the Persian element for some real fun and giggles.
Blimey some of the Ma'dan even speak Aramaic, hows that for culture eh?

South Africa: Blacks and whites do not share the same race, culture, live in different neighborhoods, do not intermarry regularly. Blacks took complete control of a government, army, police, courts which had been dominated by whites. Yet on the whole, the transition to black majority rule has been peaceful.

It could be said that the transition followed a long running low level civil war which led to the peace process.
I suppose mixing in the conflicts between the various black groups for their own political/tribal agendas might be taxing you a bit much. So how about something easier like the British/Dutch/Indian/Cape Coloured differences.
Or is it all just black and white to you?

As far as I can see, none discuss the possibility of a Shia-Sunni civil war.

So you didn't see things like.
