I'm not really sure what point you're trying to make here. Do you think it's not public knowledge that Iran finances and orchestrates Hezbollah? Or is this the terrorism card? Maybe it's different when the US supports al-Zenki et al (or the many years of financial support and hands-off permission Israel gave Hamas and then encouraged Qatar to give Hamas).
I think Hezbollah has done some truly disgusting things and I have no delusions about the ill deeds of Iran's regime. But I think it's extremely fair to say that Israel is an even more egregious perpetrator of murder, displacement, and apartheid and Iranians have every right and reason to see themselves in solidarity with Palestinians and the people of Lebanon.
