It should be a known fact by now that Ukraine asks Patriot batteries from the world - from anyone who has. And some countries do consider this option, EU Parliament even voted that the "EU" (EU members who has 'em) should give what they can. Does this Iranian attack make these countries reconsider? They obtained their systems for a reason, and while I'm sure most of them has in no real danger to get attacked, these weapons are part of their arsenal and their main job is to deter potential enemies from attacks.
