Iran's satellite should make us worry

Iran has launched its first domestically constructed satellite- and as the Pentagon observes, this is cause for grave concern.

Among other things we should be concerned for the same reason Sputnik I concerned us back in 1957: a nation with rockets capable of orbiting satellites is a nation capable of constructing a missile able to reach us.

And they're on the cusp of being able to mount a nuclear warhead on it.
