Fear of the UN arms treaty are way overblown.

In the case Reid v. Covert the United States Supreme Court rules that the Constitution of the United States supersedes any treaty ratified by the Senate.

This means, with the Heller decision safely under out belts, that firearms rights in the U.S. are safe from any treaty. Sure, such a treaty might endanger foreign arms manufacturers and imported arms, but that us easily circumvented. If this treaty is adopted by a foreign country, like Austria, for example, then look for Glock to organize a U.S. subsidiary for the domestic manufacture of Glock pistols for sale in the U.S., that is if they have not already done so.
