That is what some in the U.S. government and think tanks believe:
The idea of South Korea developing its own nuclear weapons is resurfacing among some U.S. pundits in light of the strengthened military partnership between North Korea and Russia.
However, while local analysts describe this as highly unlikely, they are skeptical about whether the growing camaraderie between North Korean leader Kim Jong-un and Russian President Vladimir Putin is significant enough to push South Korea to withdraw from its decades-long commitment to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), a move that would likely draw major international sanctions.
Allison Hooker, former senior director for Asia at the National Security Council under former U.S. President Donald Trump, suggested, Friday, that the deepening military relationship between Moscow and Pyongyang might prompt Seoul to consider pursuing its own nuclear weapons.
“I think we cannot rule out the possibility that South Korea might move more rapidly toward its own nuclear program. We need to determine how we feel about that within the U.S. and the alliance context as well,” Hooker said during a webinar hosted by the Asia Society Policy Institute.
Her remarks came a day after Republican Senator Roger Wicker called for redeploying U.S. tactical nuclear weapons to South Korea, reiterating a proposal he floated in late May.
“With our allies South Korea, Japan and Australia, we should discuss nuclear burden-sharing agreements. It’s time for them to step forward and join us in nuclear burden-sharing,” Wicker said Thursday on the Senate floor, as he spoke about the latest Kim-Putin summit.

You can read more at the link, but the ROK officials the Korea Times interviewed believe this talk is all a bluff by the U.S. side. This is because the ROK developing its own nuclear deterrent would decrase U.S. influence in South Korea. It is also believed it would cause a nuclear domino effect with Taiwan and Japan wanting their own nuclear deterrents as well.
