You do realize that such conspiracy theories require all 3 of these things to be true ?
1. American elites are totally clueless
2. The CIA is hopelessly incompetent
3. Mossad has compromised every layer of the American military and elite civilian life
Israel obviously has a ton of influence on American elites and politicians. Just the AIPAC donations and the strong representation of Jews in American elite life is proof enough. You don't have to look much further.
It's the unsubstantiated conspiracy theories (often peddled as fact) that me think there is a certain hysteria going on. It's not anti-semitism per se. More so that otherwise respectable people lose all discernment towards unsubstantiated claims when those claims support their biases about the Israel-Palestine conflict.
