In December, Secretary of State Mike Pompeo cited material evidence that Russia has quietly added nuclear-tipped missiles that are currently banned by the treaty to its colossal arsenal. He said Russia has developed "multiple battalions of the SSC-8 missiles," a move that falls outside the arms agreement.
"Its range makes it a direct menace to Europe," he said after a meeting with his NATO counterparts.
Pompeo then offered Russia an ultimatum: Come into compliance of the agreement within 60 days or the United States will exit the weapons pact.
