That sounds more like a rationalization than a reason. There is no way there is evidence of bad practices there, where they have a single payer (or some similar) health care system, and also better or different practices anywhere else. For the rationalization to be a real reason, both kinds of evidence would be needed, of bad Israeli practices and of better practices elswhere, along with data that shows those demonstrably different practices led to different outcomes, PLUS then we'd need an absence of a better alternative explanation of the different outcomes. That's a tall order under any circumstances.
