Dr. Mordecai Kedar:

"I do not buy the story that this morning's shooting in Kiryat Shmona was by 'rebellious Palestinian organizations.' In southern Lebanon, no one dares to cough in the direction of Israel without Hezbollah's prior approval. The shooting in the direction of Kiryat Shmona is the direct result of the tension in the Gulf and the threats of Israel - backed by Britain and the United States - to take revenge on Iran. 

I'm sure someone in Tehran picked up a phone to Nasrallah that night and asked him to "remind" Israelis of the pile of missiles he has and his ability to use them if Israel (or another country) does anything against Iran. And of course, he will always be able to say that these are "rebellious Palestinian organizations" ..."
