Stop it this minute or we will tell the UN on you!

The Associated Press had this caption below the photo shown here:

This satellite image provided by DigitalGlobe shows a missile on the launchpad at Musudan-ni, North Korea formally know as Taepo-dong missile launch facility. The image was collected Sunday March 29, 2009. CNN has said North Korea has begun fueling a long-range rocket for an impending launch Thursday April 2, 2009 as President Barack Obama warned the liftoff would be a "provocative act" that would generate a U.N. Security Council response.

What will the UN do besides pass on Obama’s complaint?

If firing a missile is a threat to us why don’t we shoot it shot down before it can do damage to us or to our allies? Isn’t that why we sent warships into the area?
