Is the UN Arms Trade Treaty (ATT) really a second amendment issue?

The treaty evidently tries to begin to regulate the weapons trade between nations and the 2nd amendment advocates are already claiming it violates our laws (Texas once again is at the forefront). One of the things it does is require countries to keep books on what was traded or sold, who sold it and who it was sold too. From what I gather this is one of those domino things that will eventually lead to the UN requiring a national gun registry which will then lead to a UN gun confiscation program aimed at taking away the guns of honest, law abiding, US citizens.

Really? Is this what this law is meant to do or is it another “Chicken Little” story?
