From the
Telegraph:
Iran is racing to dig a network of tunnels and upgrade its air defenses to protect its nuclear facilities from possible attacks by America or Israel, Jane's Defence Weekly reported.
Iran's supreme leader Ayatollah Ali Khamenei has issued orders for the underground complexes to be completed by the beginning of July.
The network of facilities deep underground or in the sides of mountains has been built with help from North Korean designers.
While the West dithers, Iran continues to prepare for war of a different kind than anyone has ever faced before.
