I may be mistaken, but I would suppose anyone (Goyem) could *APPLY* for Israeli citizenship. I think their point is that it would be automatically granted to persons of Jewish descent. Ireland and Italy also have this policy if I am not mistaken.
Being of a category that would immediately be accepted as a citizen is not the same thing as the nation being able to CLAIM YOU as a citizen. If a nation has you marked as a citizen, they may draft you in times of war. Obviously Israel, Ireland, and Italy (all "I's" How about that? :) ) would not grab Americans who were descended of ancestors from their nations because they have no ACTUAL claim on their allegiance.
I would suggest that if a nation can legally grab you to fight in their army, you a citizen of that nation. I would suspect that both Kenya and Indonesia could legally grab Obama and make him fight against us if they so chose. (Not now of course, but back when he was a nobody they certainly could have done so.)

OK, so you are rejecting the notion that because Romney might have been able to seek Mexican citizenship, he’s disqualified.
Basically what you are saying is that if the Mexican government had a law that actually made him a Mexican citizen, then he would be disqualified. I can understand your argument, but I still think it’s pretty lame to suggest that our Constitution would disqualify someone just because of what the law of some other land says. Suppose Iran passed a law making Obama, Romney, and the entire GOP field citizens?
I guess we can laugh that then our problems are solved, but it doesn’t make any sense from a Constitutional standpoint.
