Russia stops sharing missile test info

A senior Russian diplomat said Wednesday that Moscow will no longer inform the U.S. about its missile tests, an announcement that came as the Russian military deployed mobile launchers in Siberia in a show of the country’s massive nuclear capability amid the fighting in Ukraine.
Russian Deputy Foreign Minister Sergei Ryabkov said in remarks carried by Russian news agencies that Moscow has halted all information exchanges with Washington after previously suspending its participation in the last remaining nuclear arms pact with the U.S.
Along with the data about the current state of the countries’ nuclear forces, the parties also have exchanged advance warnings about test launches. Such notices have been an essential element of strategic stability for decades, allowing Russia and the United States to correctly interpret each other’s moves and make sure that neither country mistakes a test launch for a missile attack.
The termination of missile test warnings appears to mark yet another attempt by Moscow to discourage the West from ramping up its support for Ukraine by pointing out at Russia’s massive nuclear arsenals. It comes days after Russian President Vladimir Putin announced the deployment of tactical nuclear weapons to Moscow’s ally Belarus.
Last month, Putin suspended the New START treaty, charging that Russia can’t accept U.S. inspections of its nuclear sites under the agreement at a time when Washington and its NATO allies have openly declared Russia’s defeat in Ukraine as their goal.
Moscow emphasized that it wasn’t withdrawing from the pact altogether and would continue to respect the caps on nuclear weapons the treaty set.
The Russian Foreign Ministry initially said Moscow would keep notifying the U.S. about planned test launches of its ballistic missiles, but Ryabkov’s statement reflected an abrupt change of course.
“There will be no notifications at all,” Ryabkov said in remarks carried by Russian news agencies when asked if Moscow would also stop issuing notices about planned missile tests. “All notifications, all kinds of notifications, all activities under the treaty. will be suspended and will not be conducted regardless of what position the U.S. may take.”
Ryabkov’s announcement followed U.S. officials’ statement that Moscow and Washington have stopped sharing biannual nuclear weapons data that were envisaged by the New START treaty.
Officials at the White House, Pentagon and State Department said the U.S. had offered to continue providing this information to Russia even after Putin suspended its participation in the treaty, but Moscow informed Washington that it would not be sharing its own data.
The New START, which then-Presidents Barack Obama and Dmitry Medvedev signed in 2010, limits each country to no more than 1,550 deployed nuclear warheads and 700 deployed missiles and bombers. The agreement envisages sweeping on-site inspections to verify compliance.
