New Pentagon Strategy for U.S. Nuclear Arsenal

Pentagon unveils new nuclear weapons strategy, ending Obama-era push to reduce U.S. arsenal

The Pentagon released a new nuclear arms policy on Friday that calls for the introduction of two new types of weapons, effectively ending Obama-era efforts to reduce the size and scope of the U.S. arsenal and minimize the role of nuclear weapons in defense planning.

 From article, (The Pentagon released a new nuclear arms policy Friday that calls for the introduction of two new types of weapons, effectively ending Obama-era efforts to reduce the size and scope of the U.S. arsenal and minimize the role of nuclear weapons in defense planning. 

Defense Secretary Jim Mattis said in an introductory note to the new policy — the first update to the military’s nuclear strategy since 2010 — that the changes reflect a need to “look reality in the eye” and “see the world as it is, not as we wish it to be.”

 The previous administration’s policy hinged on what President Barack Obama called a moral obligation for the United States to lead by example in ridding the world of nuclear weapons. Officials in the Trump administration and the U.S. military argue that Obama’s approach proved overly idealistic, particularly as relations with Moscow soured. Russia, China and North Korea, they say, all advanced their nuclear weapons capabilities instead of following suit.

“Over the past decade, while the United States has led the world in these reductions, every one of our potential nuclear adversaries has been pursuing the exact opposite strategy,” Deputy Energy Secretary Dan Brouillette said at a Pentagon news conference, explaining why the United States is changing course. “These powers are increasing the numbers and types of nuclear weapons in their arsenal.”

The new nuclear weapons policy follows on Donald Trump’s promise before taking office to expand and strengthen U.S. nuclear capabilities. President Trump also vowed during his State of the Union address Tuesday to build a nuclear arsenal “so strong and powerful that it will deter any acts of aggression.” 

The policy unveiled Friday envisions the introduction of “low-yield nukes” on submarine-launched ballistic missiles. Despite being called “low yield,” such weapons could cause roughly as much damage as the bombings of Hiroshima and Nagasaki in Japan, depending on their size.

Russia possesses a wide variety of small nuclear weapons that the United States mostly lacks. The Pentagon worries Moscow could seize part or all of a U.S. ally state and then detonate one in a “limited nuclear attack” to prevent American troops from coming to the rescue. Washington would be forced to choose between launching a much larger-scale nuclear attack on Russia or responding with less substantial conventional arms. The Pentagon says it wants a proportionate weapon to match.

In a veiled reference to Russia, Rood said the new low-yield missiles would ensure that adversaries “do not come to the mistaken impression” they can use small battlefield nuclear weapons because “we don’t have credible response options.”

The new Pentagon policy also outlines longer-term plans to reintroduce a nuclear submarine-launched cruise missile called an SLCM (or “slick-em”), which the administration of President George H.W. Bush stopped deploying and the Obama administration ordered removed from the arsenal.

Officials say the SLCM would reassure Japan and South Korea in the face of threats from North Korea and put pressure on Russia to stop violating the Intermediate-Range Nuclear Forces Treaty. Unlike with the low-yield weapon, which the Pentagon plans to develop quickly, the SLCM’s reintroduction could be many years away.

The Pentagon confirmed its commitment to the modernization of the U.S. nuclear force that Obama approved in 2010 in exchange for Senate ratification of the New Strategic Arms Reduction Treaty, or New START. 

The military will introduce new bombers, submarines and intercontinental ballistic missiles, as well as a new cruise missile for the bomber. The Congressional Budget Office estimates the plan will cost about $1.2 trillion over 30 years.)
