Russia nuclear treaty: US warned over threat to scrap deal

Russia has condemned US plans to withdraw from a key nuclear weapons treaty and threatened to retaliate over the "very dangerous step".

On Saturday, President Trump said he intended to "terminate" the three-decade-old 1987 Intermediate-Range Nuclear Forces (INF) treaty.
He said Russia had been "violating it for many years".
The deal banned ground-launched medium-range missiles, with a range of between 500 and 5,500km (310-3,400 miles).

What exactly has Trump said?

President Trump said the US would not let Russia "go out and do weapons [while] we're not allowed to".
"I don't know why President [Barack] Obama didn't negotiate or pull out," the president said of the INF treaty after a campaign rally in Nevada.

In 2014, President Obama accused Russia of breaching the INF after it allegedly tested a ground-launched cruise missile. He reportedly chose not to withdraw from the treaty under pressure from European leaders, who said such a move could restart an arms race.
US National Security Adviser John Bolton is expected to confirm the withdrawal during talks in Moscow later this week.

How has Russia responded?

"This would be a very dangerous step that, I'm sure, not only will not be comprehended by the international community but will provoke serious condemnation," Russia's Deputy Foreign Minister Sergei Ryabkov said.



The treaty is "significant for international security and security in the sphere of nuclear arms, for the maintenance of strategic stability," he told state news agency Tass.
Mr Ryabkov said Russia condemned US attempts to gain concessions "through a method of blackmail".
The minister also told the news agency RIA Novosti that if the US continues to behave "clumsily and crudely" and backs out of international agreements, "then we will have no choice but to undertake retaliatory measures, including involving military technology".
"But we would not want to get to this stage," he added.
