I wouldn’t think the disorganization of Yemen on a national scale would allow them to develop something like thar kind of missile. So Iran supplying their alleged hypersonic missiles instead makes more sense. I wonder if our partner over there, the Brits, can defend against those? Would help out if yes.
There is no defense. We are told the Aegis systems of our carrier battle groups could shoot them down but we have been told many things by the MIC that turned out not to be true when finally tested.
