Who says they are going to use it against people?
Why can't they launch satellites into space?
Why can't they make missiles to protect themself against other country's?
You know what the problem of the US is? They want to control the world they want country's to do whatever they want.
And when a country refuses to do this they get pissed-off and go into war. (Iraq is an example)
Now the problem for the US is that North Korea is working on Nuclear Weapons...once North Korea has these the US will lose control...
Sorry for my English.
But anyway, If they ever do try to send 1 over, hope it hits the west coast. Kidding.
