UK Stormshadow missiles are responsible for the Black Sea Russian ship losses.
(as well, as Russia believes, crewed by UK personnel)
The announcement by Iran yesterday that they now had their own hypersonic missiles (I doubt it, more likely Russian supplied) means that it could be any day now.
My guess it will be UK ships targeted, but who knows.
i suspect Iran may put on a missile show that that would Stormin’ Normans “shock and awe” to shame, if Biden attacks Iran directly. They have no proof it was Iran that attacked, and if Iran is innocent and Biden attacks What do you suppose the response would be? Keep in mind that Iran may very well have nukes and a delivery system.
