Israel is also a fairly close ethnicity, nothing like the diversity here in the US. And they are engaged in a struggle with a specific ethnicity that they can identify.
The US has so much more diversity in population and enemies that profiling would be less effective, more annoying/discriminatory, because the "us/them" divide is less clear here.
