I might be wrong in this, but I’m pretty sure it’s exceedingly rare for Iran to directly fire missiles at Israel, it’s usually Iran-supplied proxies doing it (such as Hezbollah). It’d be like making the argument that anyone at war with a US backed nation/faction has a carte blanche to attack America
Worth noting that at this point, the Democrats were the modern Republicans. So this would be like MAGA starting a new civil war, leaving the union, and Mitt Romney arguing that a peace could be negotiated.
