Yup. but with the GPS system down you couldn't easily fix your position to target anything...
Dumb questions from me to you:
(Thinking about the AQ navy)
How are nuclear missiles timed to explode?
Does the nuke detonate even if the missile lands in the wrong spot? I'm imagining- yes.
I'm not sure that is too viable a method. A warhead big enough to to deliver a high explosive or a WMD (let's call it a nuke and not a binary chemical warhead--no spin to shatter dividers) is also big enough to produce an almost instantaneous "signature" sure to be picked up by either AWACS or a satellite or perhaps NORAD. You list the range as a couple of hundred miles. That would make it possible for the weapon to be intercepted a number of ways.
I think the Jihadists need a "sure thing" this time. They cannot risk detection or interception. Such would make 911 look too much like a fluke or a lucky sucker punch against an unsuspecting and sleeping giant. A launch from a couple of hundred miles wouldn't require a GPS. There would be internal guidance systems. It'd have to be a very sophisticated weapon. You're not talking about a simple shoulder fired STINGER that will lock-on to the heat signature of it's target. Those have a limited range and a small payload.
