If you want to understand why progress on gun violence or on other major issues facing the country has become pretty much impossible, one place to start is with the GOP's opposition to the U.N. treaty on the global arms trade. Prospects for the treaty are bleak in the United States Senate. This is because it is opposed by the National Rifle Association and Republican Senators (and at least one Democrat, Max Baucus), partly on the grounds that it will violate Americans' gun rights. Leading Tea Party Senator Ted Cruz is denouncing the treaty as international gun regulation." Senator Jim Inhofe called it "another attempt by internationalists to limit and infringe upon America's sovereignty." Last year Rand Paul claimed the treaty would pave the way for "full-scale gun CONFISCATION." These and other Senators - which may end up including a few red state Dems, too, since over 50 Senators vowed months ago to oppose it - seem to be following the lead of the NRA, which has claimed that the treaty could "infringe on gun rights as understood in the United States and could force Americans on to an international registry." Yet the treaty explicitly addresses such objections. FactCheck.org has noted that the administration has explicitly said it won't support any treaty that "regulates the domestic transfer or ownership of weapons." Gavin Aronsen adds: "the treaty doesn't dictate domestic gun laws in member countries. It requires signatories to establish controls on the import and export of conventional arms." But opposition on domestic gun rights grounds continues unabated, anyway.
