You did not get this: US Can Not Stop Iranian Missiles 04/19/2024
Let's reconsider Iran's attack. The US went through $1 billion dollars in missiles shooting down old weapons inventory that Iran had. Rather than throw it away they tossed it at Israel and Israel, the US, and Britain shot weapons costing 1,000x more at each one.
However, 7 missiles were also shot, these were the top of the line Iranian weapons and they all got through and they all did potent damage.
So then Iran sent a message, we have weapons you cannot shoot down and at the same time they sent a second message saying "your iron dome can be defeated with cheap weapons because you will go broke trying to defend yourself".
