Norad issued warnings that went out to the entire intercontinental ballistic missile ( icbm ) force and put the president 's airborne command post in the air ( without the president ) .
norad对整个洲际导弹部队(icbm)发布了警告,还让总统的空中指挥所升空(没有带总统)。
The cold war is now history , and various treaties have led to the reduction of nuclear arsenals in both the united states and russia . But the icbm is still around , and still lethal .
But the possibility of iran being able to wave a nuclear-armed icbm at american cities within two or three years cannot be discounted , and the rational behavior of president mahmoud ahmadinejad cannot be assumed .
There 's the 1980 event in damascus , arkansas , when a worker accidentally dropped a wrench into an icbm silo , puncturing a titan ii missile . It eventually exploded , blasting a 750-ton silo door a quarter of a mile away and launching the nuclear warhead into the air .
