If North Korea can send a missile and hit somewhere in the US then I'd have to give them a hand. Not only did their test make them look stupid, sort of like...
"Hey we're going to hit this US Battleship out there! *Fires missile* *Blows up 42 seconds after launch*. Oh crap, can you please move your ship closer? Our missile won't make it all the way out there to where you're at."
(I know that's not what happened, but you get the point)
But now everyone is pissed off at them.
Why would I give them a hand? Well because for right now they could make a car fly farther then what that thing did. And the US has all sorts of stuff to take missiles down (and they track everything). So North Korea would have to go from making a missile last 42 seconds to hitting somewhere in the US. Yea, that's going to happen real soon....
And they wouldn't get anywhere by striking the US. If they happen to hit the US then within a short time North Korea would be a smoking hole in the ground (our Subs have enough nukes on them that they could take out North Korea and nothing would be left).
All I got to say is, goo luck North Korea, maybe this test stuff will help feed your people!
