Of course, someone can countersue Turkey for their national soccer jersey, which has the crescent and star: Turkish National team jersey

People (condemned to repeat history, no doubt) forget that the Ottoman Empire spent nearly five hundred years trying to conquer Europe (including part of Italy). For centuries, the crescent and star were most likely a hated symbol across Eastern and Central Europe.

If this lawyer wants to return to the status quo ante, maybe Europe should insist on Turkey changing its flag before joining Europe.
