It’s not that we become anti-Iran, it’s just that it’s frustrating to see Iran get hit multiple times, assassinations, etc, and respond in limited ways with clear hesitance. They need to finally stand up to Israel. Enough is enough, but it seems like they just allow themselves to get punched.
You’re right, this attack wasn’t THAT insanely huge or anything, but it was bigger than the previous ones, and it’s going to start causing problems now because the Israelis will be emboldened by it, and keep pushing the envelope. Believe me, I hope Iran responds accordingly, but some of us have just lost hope.
