If the US alliance with Israel is the reason why this conflict generated so much protest activity, then why didn't the pro-Palestinian left object to US ally Saudi Arabia's bombing campaign and blockade in Yemen? The US arms the Saudis. Much of what happened in Yemen is very similar to what happened in Gaza (airstrikes that hit civilians, hunger caused by blockading imports, etc)

And there have absolutely been examples of mass protest movements against regimes that are hostile to the US that are committing crimes against humanity. Years ago I went to a huge demonstration about the genocide in Darfur on the national mall in Washington. Raising awareness of what is happening and putting pressure on the Iranian regime (and on Western governments) can have an impact regardless of whether or not the West is hostile to Iran.
