I mean, no one said they were? What did you think we were talking about in like at least half the comment you're replying to. I mentioned that other countries would step in several times, what did you think that meant? Like, are you just restating my comment for me? I don't get it.
Really, the only scenario where this is more than interesting world building is kind of what you mentioned though. I.e., if NATO falls apart and the US also fucks up relations with Israel leading to them ending up on Russia's side with others in some kind of World War 3 situation.
Oh man, you all are still thinking these guys have a navy at the same level as some of the top 10, none of the countries here are big enough to worry about a real aircraft carrier. Spain kind of has a singular one with a flight deck that can hold a few harriers, but they classify it as an amphibious assault ship or use it for helicopters. It's definitely the big ship to worry about in the fleet and Spain has a pretty significant complement of larger ships, but we're talking frigates, this is not that kind of Navy.
Beyond some big ships from Spain, think mostly patrol boats and a few submarines.
