Erdogan is using the deaths of 9 Turkish "activists" (read "terrorists") to further his ambitions of becoming a leading infulence in the Middle East. If he can say to the Arab world, "Here, I'm the one who got the blockade removed, while you all stood by with your hands in your pockets", he embarrasses the Arab League and gains credibility with the Palestinians and the Arab population in general. The apology doesn't mean squat to him, it's just a means to an end. The issue will not change if Israel apologizes--that's just a smokescreen for his real aim.
