Oh, he knows. To some extent.
I don’t think Netanyahu is a “true fundamentalist” like the far right part of the government. He’s Machiavellian, a suvivalist. Perhaps it’s all some means to an end, but I think Israel’s international toxicity is very much factored into his political calculus.
I don’t mean to question his faith, and I hate to sound cynical, but he’s got a looong trail of political decisions that sure speak to that.
