were planning on retaliating because of iran's on attack on israel, that certain red lines had been crossed. professor, thank you very much for joining us. israel wanted to send iran a very clear message. has that message now been received? >> they haven't done anything. there were three helicopters near isfahan that were down. there were no explosions. in no city have we had explosions. the only thing that woke me up this morning was an international reporter that called me asking what's happening, and i haven't been able to go back to sleep. so, no, we haven't seen anything in particular happen. tehran, which i'm in, the capital, is very quiet.
