Hitting targets in Iran is easy because of lack of decent AD, Air force and massive landmass, compared to Israel which roughly size of few Iranian cities with heavily protected by Israel/US/UK and NATO AD systems along with pu44y Arab leaders, so as long Iran keep the Missile barrages consistent with hitting 20-30 missiles in their major economic hubs, Iran can absorb the damage, just make sure that you return the favor without giving them much time, sooner or later they will be exhausted and Iranians are emotional like the people of subcontinent, they live to die a shaheed, they will rebuild the nation pretty quickly but hopefully Iranian leadership also tone down its rhetoric and make some good lasting friendships in region.
