I've only been to Iraq once, in the Saddam era. The war with Iran had just ended; the Baghdad Sheraton still had instructions on what to do in case of missile attack. The security forces were omnipresent, and even friends with the US and UK Embassies were nervous about security patrols despite their immunity. All in all, about the only slightly redeeming factor was the ready availability of alcohol. (I realize this falls into the "But Hitler loved dogs" level of justification, of trying to find a silver lining in the darkest of dark clouds.)
Who first invented beer and wine is debatable, but Mesopotamia and Egypt both seem to have known
But beer, wine, and arak are deeply ingrained in Iraqi society, in a way it never was in, say, Saudi Arabia. With Christians fleeing Iraq n large numbers, remaining wine-producing monasteries will see this as a new threat. And the Kurdish Regional Government, which has only the most tenuous theoretical loyalty to the Baghdad government, will likely ignore the ban.
So, I suspect, will many other Iraqis.
