The theory that it's connected to Israel sounds tenuous at best. It sounds anti-semitic at worst. Kirk was spreading American Evangelicalism which is a direct boon to Israel because the biggest non-jewish Zionists are evangelical.
I've seen the trope way too many times, where the shadowy Jews are killing the elites and are obviously responsible for everything from vaccines and autism to killing JFK to leaking war plans in the Dryfus affair. The further you get away from the nation state of Israel, the less likely I am to believe that Israel is to blame. We'll probably figure out why he was killed in the end. Or maybe not
Cut it with the crypto Nazi bullshit. You're talking out of your ass
