The analogy was apt your criticism aside.
Oddly the muslim problem persists to this day, inexplicable, eh?
To people living in the 15 C, the Atlantic ocean was as vast and unknowable as space seems to people in the 21 C.
As I said, your analogy was akin to Spain attempting to go to the moon.
“Oddly the muslim problem persists to this day, inexplicable, eh”
As far as the immediate Muslim problem to Spain in the 15th century, that problem had been taken care of with the defeat of the Moors. The problem you speak of now is a global problem unrelated to 15th century Spain directly.
You are making mixed (confused) metaphors.
