Again, this is the wrong political blackmail. You can keep blackmailing Sweden about EU membership before the Turks support Sweden NATO bid, this is not going todo anything, because Sweden is going to agree (if they agree) regardless, they aren't the member who have problem with Turkey, if Cyprus want to join NATO, then maybe Turkey can blackmail Cyprus into dropping the veto on EU for a tic-for-tac, it wouldn't work on Sweden.
Working on Sweden on something they can't do is pointless, and Turkey knows NATO will bend over backward anyway to admit Sweden, so why going for something you know is never going to happen when you can use this chance to get stuff that you can get realistically.
