Depends on the protester and what they are protesting but many of Israel protests have been against US continuing to support/fund Israel and want US government to do something different.
Iran on other hand is US sanctioned and US actively works against it, very different relationship then with Israel.
I don’t doubt that many protesters do hold this view, but looking at the banners that some protesters have it’s clear that it’s not at all universal.
