“Tunneling is something that Iran has always done better than any country in the world, throughout history, it’s an engineering fact.”
Very interesting. Have a source or two for that?
TIA!
Yeah. . .I was wondering that, too.
I thought the North Koreans had that tunneling thing down to an art and science.
The qanat system (underground aqueducts) over 3K years old and still in use today by the Persians. Ok, Iranians. Ghadffi of Libya was in process of building/adding to his underground water system when bayoneted.
Google “qanat”
Ancient Persians started civilizations first tunnels, 7th century BC:

Iran taught the world how to dig. They still have 170,000 miles of underground water conduits.
