WASHINGTON - The United States is suspending its compliance with the Intermediate-range Nuclear Forces (INF) Treaty with Russia on Saturday and will withdraw from the landmark 1987 arms control accord in six months if Moscow does not end its alleged violation of the pact, US Secretary of State Mike Pompeo said on Friday.
The United States, through a written document, will notify Russia officially on Saturday of its intention to withdraw from the Cold War-era Intermediate-Range Nuclear Forces Treaty, a senior Trump administration official said on Friday.Russia has "one final chance" to comply with the treaty, but has shown no inclination to do so despite US pressure, the official told reporters in a conference call.
Moscow reserves the right to respond to the United States' decision to withdraw from the treaty, foreign ministry spokeswoman Maria Zakharova said, according to the Interfax news agency.
Moscow is ready to maintain a dialog over the Intermediate-range Nuclear Forces (INF) Treaty, after Washington said it plans to pull out of the deal, Russian state news agency RIA reported on Friday citing a foreign ministry spokeswoman.

The United States has begun an interagency process to determine whether to seek an extension of the New START nuclear treaty with Russia when it expires in February 2021, the official said.

The treaty, which bans either side from stationing short- and intermediate-range, land-based missiles in Europe. and the INF Treaty strictly prohibits it, the officials said.
NATO allies "fully support" the United States' pending withdrawal notice from the INF nuclear missile pact over Russia's actions, a statement by the alliance said.
"The United States is taking this action in response to the significant risks to Euro-Atlantic security posed by Russia's covert testing, production, and fielding of 9M729 ground-launched cruise missile systems," it said.
"Allies fully support this action."
The United States alleges that a new Russian cruise missile violates the pact. The missile, the Novator 9M729, is known as the SSC-8 by the North Atlantic Treaty Organization (NATO).
Russia denies the allegation, saying the missile’s range puts it outside the treaty, and has accused the United States of inventing a false pretext to exit a treaty Washington wants to leave anyway so it can develop new missiles. Russia has also rejected a US demand to destroy the new missile.
US official said the US action would be "reversible" if Russia came back into compliance during the six-month US suspension. "Then the US would unsuspend," the official said.
The dispute is aggravating the worst US-Russia frictions since the Cold War ended in 1991. Some experts believe the treaty's collapse could undermine other arms control agreements and speed an erosion of the global system designed to block the spread of nuclear arms.
US Under Secretary of State for Arms Control and International Security Andrea Thompson on Thursday held last-ditch talks with Russian Deputy Foreign Minister Sergei Ryabkov in Beijing ahead of the expiration on Saturday of a US 60-day deadline for Moscow to return to compliance with the treaty.
Thompson and Ryabkov said afterwards that the two countries had failed to bridge their differences. They met on the sidelines of a meeting of the U.N. Security Council's five permanent members - the United States, Russia, China, France and Britain - all nuclear powers.
European officials are concerned about the treaty's possible collapse, fearful that Europe could again become an arena for nuclear-armed, intermediate-range missile buildups by the United States and Russia.
Russia is not prepared to restore confidence in the Intermediate-range Nuclear Forces Treaty, German Foreign Minister Heiko Maas said on Friday after the United States decided to suspend compliance with the accord."There will be less security without the treaty," Maas wrote on Twitter.
In an interview, Thompson said that suspension of US obligations would allow the US military to immediately begin developing its own longer-range missiles if it chose to do so, raising the prospect they could be deployed in Europe.
Ryabkov said Moscow would continue working toward an agreement but accused Washington of ignoring Russian complaints about US missiles and of adopting what he called a destructive position.
"The United States imposed a 60-day period during which we had to fulfill their ultimatum," the Sputnik news agency quoted Ryabkov as saying after talks with Thompson. "I conclude that the United States was not expecting any decision and all this was a game made to cover their domestic decision to withdraw from the INF Treaty."
Daryl Kimball, executive director of the Arms Control Association, a Washington think tank, said he sees little chance the treaty can be saved.
"Neither side is showing the flexibility necessary to arrive with an agreement that brings Russia into compliance," he said. "So I think it’s highly unlikely that we will see an 11th hour diplomatic miracle. "Both sides at this point appear more interested in winning the blame game than taking the steps necessary to save the treaty," he added.
Iranian Foreign Minister Mohammad Javad Zarif chided the United States on Friday for saying it may leave an arms treaty with Russia, and said on Twitter that "any deal with US (government) is not worth the ink."That treaty, which also limits deployed land- and submarine-based missiles and nuclear-capable bombers, expires in February 2021, can be extended by five years if both sides agree.

US President Donald Trump's presidency has been dogged from its inception by allegations - which Moscow denies - that Russia interfered in the 2016 U.S. election to help his candidacy. US-Russia frictions are at their worst since the Cold War ended in 1991 despite Trump's desire for better ties.

In a statement issued on Friday, Trump suggested ties could improve markedly if Russia were willing to compromise on arms control, saying all sides must live up to such agreements.

"We stand ready to engage with Russia on arms control negotiations ... and, importantly, once that is done, develop, perhaps for the first time ever, an outstanding relationship on economic, trade, political, and military levels," he said.

Senator Bob Menendez, the senior Democrat on the Senate Foreign Relations Committee, accused Trump failing to grasp the importance of arms control treaties or of having a wider strategy to control the spread of nuclear weapons.

"Today’s withdrawal is yet another geo-strategic gift to (Russian President) Vladimir Putin," he said in a statement.
