> there are 1 billion Muslims to 16 million Jews
The vasty majority of Muslims are not in the US, the area relevant to the article. Also, to complicate things, afaik most Jewish Americans oppose Israel's right wing, especially the current government, and are sympathetic to Palestinians. And afaik most Israeli support in the US is right-wing evangelical Christians (if I am defining the subgroup accurately), a much larger group than Jewish Americans.
I don't think any party has majority support in Israel, but the only reason Likud will lose the government is because someone else who promises to improve / overhaul security will win.
