"Making this treaty was like making a sausage: Everyone has added an ingredient," said Ted Bromund, a senior research fellow at The Heritage Foundation, a conservative think tank.
"Unfortunately, that has produced a document that leans much too far towards satisfying the concerns of the Arab Group and Mexico. The former view it as a rebellion prevention plan, while the latter wants a text that edges towards its view that the domestic firearms market in the U.S. should be subject to treaty regulation," he said.
But Daryl Kimball, executive director of the independent Washington-based Arms Control Association, said, "The emerging treaty represents an important first step in dealing with the unregulated and illicit global trade in conventional weapons and ammunition, which fuels wars and human rights abuses worldwide."
He said the text could have been stronger and more comprehensive, but it can still make an important difference.
"The new treaty says to every United Nations member that you cannot simply 'export and forget,'" Kimball said.
