Iraq now Immune to Authoritarian Dictatorship

So proclaimeth the Hitch. His argument? I think, therefore it is so:

Since Iraq has no choice but to be a plural and various country, these diversities can be handled in only one of three ways: by a fascistic dictatorship of one faction over all others, by civil war leading to partition, or by federal democracy. The first option has now, I think, been demolished for all time. The second two options need not be mutually exclusive or incompatible, since one is still possible and the other is still hard, and since a great deal of damage was done to intercommunal relations (to phrase it mildly) during the decades of the fascistic expedient, and since there are neighboring countries that have an interest in supporting their own religious or ethnic clienteles within Iraq.

Well, that's a relief.
