my point is that in reality it was not the smart move because he ended getting whacked, well presumably
It WAS the smart move because Tessio/Barzini hadn't counted on Vito's advisement to Michael prior to his death. That is the only reason Michael knew they were planning his assasination.
Even Michael concedes that the move Tessio made WAS the smart one, strictly in terms of business. Where he was not smart was in NOT trusting his Don...as brilliantly pointed out by SC.
It WAS the smartest move, only hitch was that Vito and Michael were just one step ahead of him.
