We’ve pulled the same shenanigans on the Israelis before. Their usually reaction is to take apart our hardware/systems, improve them considerably, and then implement a superior product. They are crafty like that. I admire anyone than hangs on in face of a ruthless enemy. It takes fortitude. Something we seem to be lacking these days.
Don't have to. Iron Dome is an Israeli product, they shared the technology with us and allowed us to build systems/components. Though I think the Defense Dept. is backing away from the system.
