Such a move states that Turkey wants a ground border link with Baghdad. I don't get why the KRG is still trying to oppose it, they are still choosing hostility and confrontation over negotiations, all that whilst they're aware they cannot win it militarily.
The KRG is ending up with less than it had after 1991, even before the 2003 invasion they had more than what it will look like soon. Baghdad as a federal authority is demanding the presence of its forces in Arbil and Suleymaniyah airport as well as all border crossings. Either way this is their fault, they have stabbed and been working on destroying Iraq whenever they were given the opportunity despite Iraq giving them autonomy and funding them with billions of dollars, they have no right to complain now.
