SANTIAGO, Chile — U.S. Defense Secretary Robert Gates said Saturday that Russian cooperation on U.S. priorities from the Afghan war to the diplomatic squeeze on Iran is at risk if the Senate doesn’t pass a new nuclear arms treaty.
Gates also said lawmakers’ failure to approve the pact would undermine the momentum for modernizing and overhauling the U.S. nuclear weapons program.
“There would be significant consequences” beyond the specifics of the U.S. and Russian nuclear stockpiles, he said while in Chile for defense meetings.
The U.S. would lose the firsthand knowledge it now gets from onsite inspections in Russia, Gates said. The wider political fallout is hard to predict, he said, but could mean less Russian cooperation with overland supply routes for the war in Afghanistan.
He noted that Russia recently approved his request to allow special mine-resistant troop carriers to cross Russia on their way to the Afghanistan front lines.
Gates also said Russia had voted with the U.S. and other allies to impose the latest round of U.N. penalties against Iran over its nuclear program. Russia is a partner with Iran in a civilian nuclear power project and generally has been less concerned than the U.S. that Iran may be hiding a bomb program.
The Pentagon chief gave a forceful defense of the treaty against Republican complaints that it limits U.S. options for future missile defense plans.
