If they ever attempted it they would be a border to border parking lot inside a week. http://www.cbsnews.com/stories/2009/10/13/world/main5380905.shtml
Then there are the kinetic space based rod weapons we may or may not have. http://www.spacedebate.org/argument/1802#1615
Iran will have a nuke, no way around it. It might better stabilize the region. Can we just remove that whole desert and shoot it into space? Lets work on that weapon. I'd short the market, it may have rallied other times, but I'd guess it wouldn't like the dollar action.
Yeah, there was a lot of yapping about the Rod from God back in the 80's when the whole Star Wars defense idea was in vogue. But, the US has actually had a device since '97 that is speculated to be able to reach hardened targets a couple hundred feet underground. Only problem is that it's thermonuclear, the B61 Mod 11. http://en.wikipedia.org/wiki/B61_nuclear_bomb
The U.S. could never use nuclear weapons again unless we are being invaded or the other side used them first against us or an ally.
Yes, they do. You're probably still the one thinking UFO's are not property of the United States Government.
You wouldn't know the difference, as the blast would be so large. Only superpowers would know for sure.
