US President Donald Trump said on Friday that he’s ordering the repositioning of two US nuclear submarines close to Russia “based on the highly provocative statements” of the country’s former president Dmitry Medvedev.

Trump posted on his social media platform Truth Social that he had “ordered two Nuclear Submarines to be positioned in the appropriate regions, just in case these foolish and inflammatory statements are more than just that.”

The president added, “Words are very important, and can often lead to unintended consequences, I hope this will not be one of those instances.” The deployment comes after Medvedev warned Trump on Thursday to remember that Moscow had Soviet-era nuclear strike capabilities of last resort.
