Seriously, the treason bit is a bit much.
read this thing and replace Jews/Israel with say, Russians. imagine if there were a few dozen Russian-American congressman who formed an unofficial "caucus" across party lines and regularly flew back to Russia to laud the way their gov't was "protecting the Russian people" through its actions in Ukraine. and imagine these Congressmen took campaign money from the American-Russian Public Affairs Committee and frequented its K Street offices.

as for the rest, I'll note that I, at least in theory could face the same dangers you do from the "rise of global antsemitism". I have Jewish ancestry and would have been considered a Jew by the Nazi legal definition. my borderline hatred for the State of Israel and the role it plays on the world scene is not unrelated to my pseudo-Jewish background.
I think most Jewish people think that Israel's interests and the USA's interests basically overlap and believe that it's a moral imperative to stand up for Israel, not a religious or ethnic imperative. It's interesting personally how this all shakes out. I actually went to undergrad at a super liberal hippy school and there was a real anti-Israel undercurrent. But, when I went to an ivy league grad school you could tell that the ruling class of America, as opposed to the humanities professors and intellectual stoners, truly support Israel in a strong way. It's an interesting dynamic and I'm curious to see how this whole debate shakes out as the US gets more polarized and Israel gets more conservative and insane.
And, don't think being self-hating makes you any less Jewish, it makes you more Jewish. That's how we get you.
You could say that about virtually any Western country that a lot of Americans have ancestral ties to - Great Britain, Germany, France, Japan, the Netherlands - but we never hear about, say, the British-American Political Action Committee.
