WASHINGTON • US President Donald Trump's administration has discussed holding the first US nuclear test since 1992 as a potential warning to Russia and China, The Washington Post reported on Friday.
Such a test would be a significant departure from US defence policy and dramatically up the ante for other nuclear-armed nations. One analyst told the newspaper that if it were to go ahead, it would be seen as the "starting gun to an unprecedented nuclear arms race".
The report, citing one senior administration official and two former officials, who spoke anonymously, said the discussion had taken place at a meeting on May 15.
It came after some US officials reportedly claimed that Russia and China were conducting their own low-yield tests. Moscow and Beijing have denied the claims and the US has not offered evidence for them.
The senior administration official said that demonstrating Washington's ability to a "rapid test" would be a useful negotiating tactic as the US seeks a trilateral agreement with Russia and China over nuclear weapons.
The meeting did not conclude with any agreement and the sources were divided over whether discussions were still ongoing.
Nuclear non-proliferation activists were quick to condemn the idea. "It would be the starting gun to an unprecedented nuclear arms race," Mr Daryl Kimball, executive director of the Arms Control Association, told the Post.
He added that it would also likely "disrupt" negotiations with North Korean leader Kim Jong Un, "who may no longer feel compelled to honour his moratorium on nuclear testing".
The Trump administration has repeatedly shaken up US defence policy.
The Washington Post report came one day after Mr Trump announced that he plans to withdraw from the Open Skies treaty with Russia. The treaty seeks to lower the risk of war by permitting each signatory country's military to conduct a certain number of surveillance flights over another member country each year on short notice.
Facing re-election in November, Mr Trump has significantly hardened his rhetoric against China in recent weeks, repeatedly criticising Beijing's handling of the coronavirus pandemic which first emerged in Wuhan province.
He has made repeated but vague threats of retaliation against the chief US economic rival, which has denied all his accusations.
Earlier this month, Mr Trump called for involving China in new arms control talks with Russia, telling Russian President Vladimir Putin that they need to avoid a "costly arms race".
It is not the first time Mr Trump's defence policy has raised concerns that the administration is elevating the risk of nuclear war.
In February, the Pentagon announced that it had deployed a submarine carrying a new long-range missile with a relatively small nuclear warhead, saying it was in response to Russian tests of similar weapons.
Critics worry that small nukes would be more likely to be used because they cause less damage, thereby lowering the threshold for nuclear conflict.
