The internet contains a swamp of hackers both domestic and foreign that 
would love to get it hands on a missle.  You ever heard of terrorist. So, to 
control a missle on the internet is treason type of programming.

The guidance system may use GPS but that just a series of numbers from 
transmitted by a group of satellites through a set of radio frequences that is 
finally transfer into the system by a serial/parallel/"memory mapped" port. 
And that's not an IP or the internet connection.

Then during a short time after launch the missile might have a kill switch 
but that would be secure radio or laser frequence with another port on the 
system.
