ATT isn't dead, the Administration cowards just wanted

to delay it.
UPDATE: According to Colum Lynch, UN reporter for the Washington Post and Turtle Bay blogger for Foreign Policy Magazine, the US isn't actually refusing to sign the ATT. They and the Russians are putting out a joint statement saying that they need more to study the proposed treaty. From his Tweet on the subject, "UN diplomat said Washington wants to put off action on a new arms trade treaty, after the US election."

From his blog :

The United States upended a major international treaty negotiation, telling foreign delegates at the final session today that they needed more time to consider the pact. Some diplomats said that Washington is seeking another six months, pushing off any decision on the politically sensitive treaty until after the U.S. election. Russia, Indonesia, and India also asked for more time.

Thomas Countryman, U.S. deputy secretary of state for international security and nonproliferation, informed representatives of the U.N.'s 193 member states that the United States still needed time to consider the text.

He continues:

The United States told delegates that it did not have "core" objections to the draft treaty under consideration, but that it needed more time, saying that while the U.N. negotiations have been playing out since July 2, they only received the final text in the past 24 hours.

In my opinion this is something for great concern. That the US doesn't have "core" objections and wants to wait until after the election spells trouble for gun rights. I say this because they have no real objections to a treaty that, despite their denials, has negative implications for the Second Amendment. Moreover, putting it off until after the election means a treaty could be approved by a lame duck US Senate. This may seem paranoid but I don't trust either Obama or his State Department on this issue.

I'd figured the 'won't sign' crap was because of heat on the upcoming election; I was right.
