The UN is still working on a proposed draft of the Small Arms Treaty and the next meeting on it isn't until 2012. If you want something to worry about, look at the CIFTA Treaty
. It has already been signed (by Clinton) and ratifying it was something that President Obama listed as one of his top 19 priorities in 2008.
Which is not to say we don't need to be concerned about the UN Small Arms Treaty; but at this time I would rate it lower in priority than the ongoing Second Amendment litigation, the impending Executive Orders affecting firearms, and the ATF run amok in Gunwalker.
