Weird article.
The Iron Dome system is not American. Israel rejected Patriots as being inferior. The interceptors mentioned are not American. Not clear how the US could rush anything.
The U.S. Army purchased several Iron Dome batteries and Raytheon is producing more in the U.S. under contract:

Iron Dome aerial targets that can be met by Iron Dome anti-air weapons, are served by those Iron Dome anti-air weapons.
Both anti-air systems - Iron Dome and Patriot - have been working together for some HAMAS attacks - when Iron Dome itself, is found to be in need of Patriot missiles, because Iron Dome does not have enough of its own anti-air weapons available.
