Israel also admits to doing cancer research. That doesn’t automatically make cancer good, it just means that one of their many enemies also happens to be a bad thing. Obviously, Israel will want to support any enemies of their enemies, and will be willing to force the hand of their enemies in ways that make them look bad on the international stage to make their future attacks more palatable. That doesn’t mean that the only people in Iran who don’t support the government are Mossad assets.
