"The only ones applauding the decision to tear up the INF Treaty are the nuclear weapons manufacturers, eagerly anticipating the kickoff of Cold War II".
At a news conference, Pompeo said Russian Federation has weapons that violate the terms of the 1987 Intermediate-Range Nuclear Forces treaty - putting, he said, millions of Americans and European allies at risk.
Technically, a USA withdrawal would take effect six months after this week's notification, leaving a small window for saving the treaty.
The official said if that happens "then the United States would unsuspend".
The United States alleges that Russia's 9M729 missile is in violation of the INF treaty because it operates in a prohibited range.
"Blowing up the treaty risks the proliferation of nuclear-capable systems by Russian Federation, threatening Europe and jeopardizing decades of bipartisan efforts to reduce nuclear dangers with Russian Federation". Russian Federation denies the USA allegations, accusing Washington of making a nuclear war more likely.
However, Pranay Vaddi, a former US diplomat who worked on arms control for the State Department, said the United States would be hard-pressed to find allies in Asia willing to house intermediate-range missiles, nuclear or not.
Reif said the period between now and August, when the USA withdrawal would take effect, offers a last chance to save the treaty, but he sees little prospect of that happening.
"We can not be the only country in the world unilaterally bound by this treaty, or any other".
"It is our duty to respond appropriately", Pompeo said, adding that the U.S. had provided "ample time" for Russian Federation to return to compliance.
Pompeo and Trump said that USA allies in Europe were with them, with Trump's statement saying, "Our NATO Allies fully support us, because they understand the threat posed by Russia's violation and the risks to arms control posed by ignoring treaty violations". Russian Federation has also rejected a USA demand to destroy the new missile. "This is fully about Russia's violation to his treaty". Robert Menendez, acknowledged Russia was in breach but said the Trump administration lacks both an understanding of arms control treaties and a coherent strategy to face the threat new Russian cruise missiles to US interests and allies.
"China [and] Iran, for that matter, are not bound by the treaty", said the senior administration official on the phone call with reporters. "It is a reality that China is unconstrained, it is a reality they have more than 1,000 of these weapons, but for the United States this has nothing to do with China".
"Russia will feel more legitimized to continue what it's doing now, but also increasing some of its efforts on missile technology and deploying them", said a European official.
A senior Trump administration official told reporters on February 1 that the exit from the treaty has nothing to do with China, which has deployed more than 1,000 missiles neither Washington nor Moscow could deploy under the INF.
