US ready to use nukes in case of conventional attack - Nuclear Posture Review

The US is more likely to use nuclear weapons, according to the new Nuclear Posture Review (NPR) just released by the administration of President Donald Trump.

Washington’s new Nuclear Posture Review (NPR) recommends a hawkish approach to cooperation with Russia over nuclear proliferation, and further calls for the US to tackle “an unprecedented range and mix of threats” posed by foreign powers including Russia, China, North Korea and Iran.

A key shift from existing nuclear weapons policy is the expansion of scenarios in which a nuclear threats would be considered. The document lists non-nuclear attacks that could constitute grounds for US nuclear retaliation. Under the new NPR, a conventional attack which results in mass casualties or targets key infrastructure could trigger a nuclear response.

The review suggests a hawkish approach to cooperation with Russia over nuclear proliferation.  It warns that Russia is “developing and deploying new nuclear warheads and launchers” and will “continue to increase its warhead delivery capacity” in the future.

Washington finds “troubling” Russia’s adoption of military strategies and capabilities that rely on nuclear escalation, according to the NPR.

"Russia has demonstrated its willingness to use force to alter the map of Europe and impose its will on its neighbors, backed by implicit and explicit nuclear first-use threats," the report says.

"We do not want to regard Russia as an adversary," said Acting Assistant Secretary of State for Arms Control, Verification and Compliance, Anita E. Friedt said at the NPR roll-out at the Pentagon on Friday. “This not a Russia-centric NPR."

The US “remains committed to the moratorium on nuclear testing." National Nuclear Security Administration Administrator Steve Erhart added.

The review also calls for more integration between nuclear and non-nuclear forces, and upgrading F-35 fighter aircraft to carry nuclear bombs and missiles.

“The strategy develops capabilities aimed at making use of nuclear weapons less likely,” the White House said on a statement on Friday. “It enhances deterrence of strategic attacks against our Nation, and our allies and partners, that may not come in the form of nuclear weapons.”

Many experts have greeted the NPR with skepticism, however. Adam Mount, senior fellow at the Federation of American Scientists, accused the review of reflecting a “slanted view” of the world and an “obsolete theory of deterrence and war fighting.”

“Rather than working to reduce nuclear dangers, the nation’s nuclear policy now reflects the reasoning of US adversaries and readily follows them into a more dangerous world,” Mount wrote in Foreign Affairs magazine on Friday.

Hans Kristensen of the Federation of American Scientists also took issue with the nuclear modernization chart featured in the NPR, calling it “grossly misleading.” He offered a corrected version, which reflects US modernization efforts as well.

Jon B.Wolfsthal, a former US government official now leading the Nuclear Crisis Group, pointed out that the NPR had a bit of an exceptionalism problem.
