PALM BEACH, Florida – U.S. President-elect Donald Trump called on Thursday for the country to expand its nuclear weapons capabilities until the world “comes to its senses” — a signal he may support costly efforts to modernize the aging U.S. nuclear arsenal.
It was not clear what prompted his comment. However, earlier on Thursday, Russian President Vladimir Putin said that Russia needed to “strengthen the military potential of strategic nuclear forces.”
In a post on Twitter, Trump said, “The United States must greatly strengthen and expand its nuclear capability until such time as the world comes to its senses regarding nukes.”
Trump, who is in Florida for the Christmas holiday, gave no further details. Asked about the tweet, a spokesman said later Trump was “referring to the threat of nuclear proliferation and the critical need to prevent it — particularly to and among terrorist organizations and unstable and rogue regimes.”
Trump also has “emphasized the need to improve and modernize our deterrent capability as a vital way to pursue peace through strength,” spokesman Jason Miller said.
During the next decade, U.S. ballistic missile submarines, bombers, and land-based missiles — the three legs of the nuclear triad — are expected to reach the end of their useful lives. Maintaining and modernizing the arsenal is expected to cost at about $1 trillion dollars over 30 years, according to independent estimates.
Putin, who has said that Trump has confirmed to him he is willing to mend ties between the two countries, spoke on Thursday of the need to enhance the country’s nuclear arsenal.
“We need to strengthen the military potential of strategic nuclear forces, especially with missile complexes that can reliably penetrate any existing and prospective missile defense systems,” he said in a speech in Moscow.
Trump, who won election on Nov. 8 and takes office on Jan. 20, campaigned on a platform of building up the U.S. military, but also pledged to cut taxes and control federal spending. He has also said he wants to improve relations with Russia.
Trump met on Wednesday with a dozen Pentagon officials involved with defense acquisition programs, as well as the chief executives of Lockheed Martin Corp and Boeing Co, the country’s two largest defense contractors.
Trump said he talked with the CEOs about lowering costs for two high-profile programs: Lockheed Martin’s F-35 fighter jets and Boeing’s replacement 747-8s for the presidential Air Force One plane.
The United States is one of five nuclear weapons states allowed to keep a nuclear arsenal under the Nuclear Non-Proliferation Treaty. The others are Russia, Britain, France and China.
Most of the U.S. arsenal was built between 25 and 62 years ago during the arms race with the former Soviet Union, and has been patched and otherwise refashioned many times to extend its lifespan.
“It’s not a choice between replacing these platforms or keeping them — it’s really a choice between replacing them or losing them,” Defense Secretary Ash Carter said in September during a visit to a North Dakota air force base where missiles are kept, noting that Russia had built new missile systems.
Modernizing the arsenal will cost $348 billion through 2024, the Congressional Budget Office has said. Some of the costliest upgrades would come after that point. But even at its peak, spending on the nuclear program would make up only about 5 percent of the Pentagon’s budget.
Defense stocks were little changed after Trump’s tweet, but shares of small uranium miner Uranium Resources Inc Uranium Energy Corp jumped.
