After months of finger pointing, the Trump administration has made it official: It will formally notify Russia that the United States is withdrawing from a Cold War-era nuclear treaty, over what the administration says are violations by Moscow.
It's called the Intermediate-range Nuclear Forces treaty and it restricts missiles capable of striking Europe on short notice.
(SOUNDBITE) (English) U.S. SECRETARY OF STATE MIKE POMPEO, SAYING: "Russia has jeopardized the United States security interests and we can no longer be restricted by the treaty while Russia shamelessly violates it.
If Russia does not return to full and verifiable compliance within the treaty within the six month period by verifiably destroying its INF violating missiles, their launchers and associated equipment the treaty will terminate." This was Russia's very public attempt to prove that its cruise missile system doesn't violate the arms treaty.
But last week's televised demonstration clearly hasn't had the desired effect.
The U.S. says the system isn't compliant because of its long range.
And has accused Russia of destabilizing global security by refusing to destroy it.
Moscow maintains that Washington invented the violation in order to exit the agreement - something that would allow the U.S. to develop its own new missiles.
Last-ditch talks in Beijing failed to resolve the impasse.
