Symbolism of the "Iron Dome" Missile Defense Shield of Israel

You hear a lot about the “Iron Dome” missile defense shield of Israel, and how the commitment of the United States to defend Israel from people they have been systematically killing for generations is “Ironclad.”

Why was the name “Iron Dome” chosen though? Have you ever thought about that?

As best I can tell, the symbolism of the words “Iron Dome” means that Israel controls the Congress of the United States.
