The United States has informed Russia it will not exchange data on its nuclear forces, a White House spokesperson said on Tuesday, describing the change as a response to Moscow's decision to suspend participation in the New START nuclear arms treaty.
"Under international law, the United States has the right to respond to Russia's breaches of the New START Treaty by taking proportionate and reversable countermeasures in order to induce Russia to return to compliance with its obligations," a spokesperson for the National Security Council said.
"That means that because Russia's claimed suspension of the New START Treaty is legally invalid, the U.S. is legally permitted to withhold our biannual data update in response to Russia's breaches," the spokesperson added.
