It doesn't really matter if his identity gets leaked, when you are a director, you always become more visible no matter what you do. You cannot hide if you are a director.

In military matters, high ranking officers don't protect their identity, because they represent the military.

Although it is obviously true that lower and medium ranking soldiers and personnel ALWAYS need to protect their identity, because they should not be identified since they are the ones who carry orders and take the real risks.

Of course it would have been better for him to not have his identity disclosed, since it would expose him to assassins if he would travel, but honestly this is a non-story, this will just generate hate comments in anti-israel crowds.
