Ted Cruz accused the Obama administration of forbidding US airlines to fly into Tel Aviv in order to pressure Israel over the Gaza strip. He might have something there. The flight ban was laid on after a Palestinian rocket hit within a mile of the airport. Which is not nearly as dangerous to aircraft as a SAM.
Fortunately FAA dropped the flight ban to Tel Aviv after two days, which makes me think maybe they were really thinking about flight safety rather than retaliation.
That a responsible US Senator would make such a charge indicates a major loss of trust with the Obama Adminstration.
