Russian Deputy Foreign Minister Sergey Ryabkov has cautioned that Moscow is considering a range of potential actions related to nuclear testing, criticizing the extreme position held by President-elect Donald Trump. Ryabkov highlighted the strained international relations and indicated that Russia would not exempt any measures necessary to ensure its security. He referenced discussions during Trump’s first term about the possibility of the U.S. conducting its first nuclear test since 1992, which could lead to reciprocal actions from Russia.
