This article is propaganda.
1. The source is a supposed anonymous, unnamed Israeli defense source.
2. While giving the appearance of using facts, the facts reported are irrelevant. It makes no difference to this airstrike issue that the Mossad chief was asked to remain in office. It makes no difference that a military person had the Iran issue placed under his watch....of course it was under someone's watch. Neither of those 2 facts have anything to do with an anonymous report about an Israeli airstrike against IRan.
3. The Israeli Defense Minister denies claims such as these.
This is someone in either Britain or Israel attempting to undercut any attempt by Israel to launch a pre-emptive strike against Iran.
It could be - or it could be purposely leaked by Israel as a threat to Iran - i.e - if you don't stop, we can now strike you at any time we choose. Stop or else.
