The Mossad operation is brilliantly coordinated and flawlessly executed, except that it was recorded and available for analysis. There are clear videos, photos and analysis of the not so secret agents. That is not considered a good thing in most clandestine operations.
Claims that Mossad knew they were being recorded is laughable and absurd. You can look at this remarkable video and decide for yourself.
I am certain Mossad has watched this hundreds of times and realizes that in the future, Dubai may not be the best place to make a hit and still protect your agents.
I have no ethical problem with a controlled state sponsored killing of an enemy, but the wisdom and ethics of using passports from unwary and uninvolved civilians is astonishing to me.
There can be no possible up side to such a foolish decision. However, I wait in eager anticipation for any explanation or theory that has so far eluded me.
