Israel is “74.2% Jewish, 17.8% Muslim, 2.0% Christian, and 1.6% Druze. The remaining 4.4% included faiths such as Samaritanism and Baháʼí as well as "religiously unclassified", the category for all who do not belong to one of the recognized communities.” So, it arguably has more religious diversity than the US.
The US is largely Christian with no other religion making up more than 2% of the population.
