all they have to do is ignore Obama's warning and follow their policy and sue Israel in International courts. You remember President Gul's wife Hayrunisa hanim had sued Turkey over the head scarf. It is easy. Now ask yourself why Erdoan is not doing that? Israel does not want an international probe because they do not want their military weaknesses to be exposed. They will deal with it internally learn the lessons and fix it for the next time that's all.
