New US nukes concern experts

- Thomas Watkins

THE Pentagon is set to unveil President Donald Trump’s nuclear policy next week, and critics are already warning it could trigger another arms race and raise the risk of miscalcula­tions that might spark an atomic conflict.

A leaked draft version of the Nuclear Posture Review indicates the Pentagon is calling for the developmen­t of a new type of low-yield nuclear bomb that is designed to be used on the battlefiel­d, rather than to level a city.

These so-called tactical nuclear weapons have a limited explosive strength – though still are staggering­ly powerful compared to convention­al weapons.

Underpinni­ng the Trump nuclear doctrine is the concern that America’s nukes are so powerful that adversarie­s don’t believe they would ever be used.

The draft policy says Russia’s own lowyield nukes, within easy striking distance of Europe, provide “a coercive advantage in crises and at lower levels of conflict”.

“Correcting this mistaken Russian perception is a strategic imperative,” the document states.

Any weapon with an explosive blast of 20 kilotonnes or less is considered low-yield. To put that in perspectiv­e, 1 kilotonne is the same as 1,000 tonnes of TNT; the bombs dropped on Hiroshima and Nagasaki at the end of World War II were about 15 and 20 kilotonnes respective­ly, so they would be considered lowyield today.

But America already has a massive nuclear arsenal at its disposal, including 150 B-61 nukes stored across multiple European countries that can be configured for low-yield options.

Hans Kristensen, director of the nuclear informatio­n project at the Federation of American Scientists, said the existing US military strategy does not need a new type of weapon.

“If you really wanted to use weapons in a limited low-yield scenario, they are there. You don’t have to have another one,” he said.

Escalate to de-escalate

Given the state of Russia’s military forces and the country’s financial problems, Moscow fears it would be quickly outmatched in a convention­al conflict with the West.

To compensate, it has an “escalate to de-escalate” strategy in which it would deploy lower-yield bombs as part of a limited first use of nuclear weapons.

The Pentagon’s nuclear policy draft, which euphemisti­cally calls low-yield bombs “supplement­s”, states that increasing such weapons would help deter Russia and other nations.

“These supplement­s will enhance deterrence by denying potential adversarie­s any mistaken confidence that limited nuclear employment can provide a useful advantage over the United States and its allies,” states the policy, which was obtained by the Huffington Post.

Kristensen said he could envision a scenario where a US president was “less self-deterred” from using a nuclear weapon if he thought it would only have limited effects on a civilian population.

The proposed policy says the Defense Department and the National Nuclear Security Administra­tion will develop a low-yield submarine-launched ballistic missile for deployment and, in the longer term, develop a sea-launched cruise missile.

America currently has an estimated arsenal of about 7,000 nuclear warheads, second only to Russia, which has a few hundred more. The new missile types wouldn’t add to the stockpile, but rather would reconfigur­e existing warheads.

Critics, including Democratic lawmakers, worry not just about developing new weapons but of the cost of overhaulin­g America’s nuclear arsenal. Already, the price tag is more than $1 trillion over 30 years. Congressma­n Adam Smith, the top Democrat on the House Armed Services Committee that oversees the Pentagon, blasted the new policy.

“The administra­tion’s recommenda­tions will not increase our security,” Smith said. “They will instead feed a nuclear arms race, undermine strategic stability by lowering the threshold for nuclear use, and increase the risk of miscalcula­tion that could precipitat­e a nuclear war.”

Matthew Costlow, a defence analyst at the National Institute for Public Policy, said fears are being overblown.

“The nuclear order is not so fragile as to be shaken by the modificati­on of a few warheads by a responsibl­e nuclear power such as the United States,” he wrote in an opinion piece published by the Breaking Defense news site.

“In fact, there is evidence it could reduce the chances of nuclear war by making aggressive nuclear states like Russia and North Korea think more than twice about escalating a failing conflict.”

The new conversati­on marks a significan­t departure from the talking points of the administra­tion of Barack Obama, who during a famous speech in Prague in 2009 called for the eliminatio­n of nuclear weapons.

In 2010, Obama and Russia’s thenpresid­ent Dmitry Medvedev signed the so-called New START treaty that calls for a significan­t reduction in the nuclear arsenals of both countries. That deal expires in 2021, when Trump could potentiall­y be serving a second term. Barry Blechman, co-founder of the Stimson Center, a nonpartisa­n anti-nuclear proliferat­ion think tank in Washington, said he was worried some of the language in the draft nuclear policy would make it harder to renew that treaty.

“I am very concerned,” he said. “It’s a step toward this direction of fighting nuclear wars as a realistic option.”
