What an interesting idea -- and I was completely unaware that a Kurdish flag even existed! Where can I find one?
Of course, given that U.S. policy has always been to deny the Kurds a state of their own, it will probably be a cold day in Hell before it happens.
'Kurdistan' covers chunks of territory from five different nations (Iran, Iraq, Syria, Turkey and Russia) and sits atop a treasure-trove of oil. None of the five is likely to be willing to give up their piece of the Kurds' traditional lands, especially Turkey, who have been forcefully suppressing them for a very long time. I'd even suspect that the Turkish resistance to a Kurdish state was the primary reason that, during the Iran/Iraq war prior to the Shah's ousting in 1976, the CIA (headed by none other than Dubya's dad) engaged in a deliberate policy to encourage Kurdish resistance to Iraq's Baathist regime -- while ensuring that they were NOT given enough support to actually topple the Iraqi government.
This policy, BTW, is the precise reason that the Baathists first began to seriously hunt the Kurds, which makes the 'righteous indignation' (of both Bush and Shrub) over Saddam's brutality toward the Kurds one of the most sickening examples of realpolitikal hypocrisy I've ever heard of.
For those who want verification of this, please refer to the Pike Commission report of 1980. ;-}
