You can’t blame them for not wanting to sell it to the US. The US defense industry and military is so infiltrated with traitors and spies that nothing is really secret anymore. The CCP knows about everything we have.
Iron Dome is actually a development of an existing Raytheon system and is manufactured by Raytheon and Rafael both in the US and Israel.
I dunno about Iron Beam but the US has been doing directed energy for decades. Every hear of "Star Wars"? It was a little program Mr. Raygun helped fund. Took down the USSR.
Well, yeah. That's partly because of Israel.
