Hamas is financed and armed by Iran. Iran has a keen interest in observing and studying Iron Dome in action. The Iranians know that unless their ballistic missile counterattack penetrates Israel’s defenses and causes devastation, Israel will destroy Iran’s nuclear infrastructure methodologically. Egypt is financially dependent on the Saudis. The Saudis want Hamas degraded. They actually want Israel to successfully destroy Iran’s nuclear capabilities and will provide covert aid. The Palestinians are being played as pawns.
I believe the Iron Dome is for short range rockets, while Iranian rockets would be intercepted by another and different system.
