Former Mossad chief Meir Dagan said that "no red lines exist with regards to Iran."

"I don't think that a military strike is enough to stop the (Iranian nuclear drive)," saying that the knowledge accumulated by Iranian scientists will remain.

Dagan also stated that he believes the IAF has the capability of carrying out an attack on Iranian nuclear facilities. "The question is what happens five minutes after an attack," Dagan said, adding that an attack would rally the Iranian people, whereas sanctions, which started under previous governments and has been bolstered by the current US administration, have been working.
