I offer two possibilities:

1. Iran has frequent large protests that consistently get crushed. So while I assume the vast majority of Americans oppose the Iranian government, it’s hard to get worked up for the 5th, 6th time.

2. The US doesn’t support the Iranian government. We already sanction them. What additional support can US citizens lobby for? In the case of Israel, decreased US support would have a tangible effect. Unclear how increased US support for Iranian protestors would matter.
