Ernest Moniz has a suggestion for the incoming Trump administration.

The outgoing Secretary of Energy wrote an editorial for the journal Science suggesting the best strategy for banning nuclear weapons tests in other countries would be to ban them at home.

Moniz explains a key component of this policy would be to revisit the Comprehensive Nuclear Test Ban Treaty, which proposed a ban on nations attempting to explode nuclear weapons in order to test them, according to The Verge.  

The agreement was adopted by the United Nations General Assembly, but never ratified by members of the UN Security Council like the U.S. and China.

Furthermore, the U.S. Senate analyzed the deal in 1999 choosing to not ratify it because Moniz noted two principal objections needed to be addressed at the time.

“The newly created science-based stockpile stewardship program, designed to replace nuclear test explosions with an integrated scientific program of computer simulations, data analysis and laboratory tests of weapons subsystems, was at least a decade away from having its suite of new tools in place. There was also uncertainty about the ability to detect low-yield clandestine underground tests anywhere in the world,” the secretary wrote.

Technology has evolved over time granting the U.S. the ability to use tools like sophisticated supercomputer simulations to maintain the security and stability of the country’s arsenal without needing to detonate any ordnance.

“Incredibly sensitive measurements can now detect and identify radionuclide signatures associated with nuclear explosive tests, including low-yield or evasive tests. With the treaty in force, international experts will conduct an on-site inspection after a suspect event,” the secretary wrote mentioning there are tools in this place to monitor detonations all over the world as well.

Essentially, Moniz writes that obtaining legislative approval for this treaty would lay the groundwork for a global ban and provide the U.S. and its partners with a better foundation for enforcing tougher sanctions on countries like North Korea when it initiates these destructive programs.
