Matt Bracken compares the rhetoric about Iran to the 2005 talking points regarding North Korea's nuclear program. He argues that Iran is 14 times larger than North Korea and possesses mountain complexes bored into thousands of feet of solid granite. Bracken asserts that U.S. bunker-buster bombs are ineffective against these facilities and that a ground invasion would require a drafted army of millions to face a "Swiss-style" mountain defense.
