If your adversary is the Mossad, or some equivalent thereof, they are going to do Mossad things to you, and you're going to die and there's nothing that you can do about it. That's a bit hyperbolic. An institution like the Mossad has literally thousands if not millions of "adversaries". They don't kill all of them. They probably kill less than 1% of them. There's plenty of downside to killing someone. E.g. in 2010 the Mossad horribly botched an assassination: http://www.dailymail.co.uk/news/article-1261435/How-Mossad-blew-The-gripping-story-Israels-brutally-efficient-secret-service-botched-Dubai-assassination.html http://www.dailymail.co.uk/news/article-1261435/How-Mossad-b... If even 1% of their assassinations went that badly, the PR fallout would be devastating. I'm sure they're quite selective over who is "going to die". Call me a stoic or a fatalist or an idiot, but this is not something I'm concerned about when I'm crossing a border. There's a 100x greater chance, or maybe a 1,000,000x greater chance that the Mossad (or equivalent) compromise your phone than decide to kill you.
