The Kurds are involved in several Middle East dramas at the moment. Yet they live in multiple countries across the region and are playing different roles in different places.
In Iraq, Kurdish fighters are working closely with the U.S. to battle the Islamic State.
In Syria, the Kurds are also fighting the Islamic State, but until U.S. air drops this week, the U.S. had been reluctant to work directly with the Syrian Kurds.
Then there are the Turkish Kurds, who have been seeking to join the battle, but have been blocked from doing so by Turkey.
