The US will withdraw from a landmark nuclear weapons treaty with Russia, President Donald Trump has confirmed.
Speaking to reporters, Mr Trump said Russia had “violated” the 1987 Intermediate-Range Nuclear Forces (INF) treaty.
The deal banned ground-launched medium-range missiles, with a range of between 500 and 5,500km (310-3,400 miles).
The US would not let Russia “go out and do weapons [while] we’re not allowed to”, Mr Trump said.
“I don’t know why President [Barack] Obama didn’t negotiate or pull out,” the president said after a campaign rally in Nevada. “They’ve been violating it for many years.”
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.
A Russian foreign ministry source said the US move was motivated by a “dream of a unipolar world” where it is the only global superpower, state news agency RIA Novosti reported.
The US insists the Russians have, in breach of the deal, developed a new medium-range missile called the the Novator 9M729 – known to Nato as the SSC-8.It would enable Russia to launch a nuclear strike at Nato countries at very short notice.
Russia has said little about its new missile other than to deny that it is in breach of the agreement.
Analysts say Russia sees such weapons as a cheaper alternative to conventional forces.
The New York Times reported on Friday the US was considering withdrawing from the treaty in a bid to counter China’s expanding military presence in the western Pacific.
The country was not a signatory of the deal, allowing it to develop medium-range missiles without restraint.
National Security Adviser John Bolton is expected to tell the Russians of the withdrawal during talks in Moscow later this week.
What is the Intermediate-Range Nuclear Forces (INF) treaty?
Signed by the US and the USSR in 1987, the arms control deal banned all nuclear and non-nuclear missiles with short and medium ranges, except sea-launched weapons
The US had been concerned by the Soviet deployment of the SS-20 missile system and responded by placing Pershing and Cruise missiles in Europe – sparking widespread protests
By 1991, nearly 2,700 missiles had been destroyed. Both countries were allowed to inspect the others installations
In 2007, Russian president Vladimir Putin declared the treaty no longer served Russia’s interests. The move came after the US withdrew from the Anti-Ballistic Missile Treaty in 2002
The last time the US withdrew from a major arms treaty was in 2002, when President George W Bush pulled the US out of the Anti-Ballistic Missile Treaty, which banned weapons designed to counter ballistic nuclear missiles.
His administration’s moves to set up a missile shield in Europe alarmed the Kremlin, and was scrapped by the Obama administration in 2009 to be replaced by a modified defence system in 2016. BBC News.
