US President Donald Trump said Friday he was ordering two US Navy nuclear submarines to “appropriate regions,” in response to remarks by Dmitry Medvedev, Russia’s former president and current deputy chairman of its Security Council.

In 2017, during his first term as US president, Trump announced that he had sent two nuclear submarines to the Korean peninsula. Soon afterwards, he held a meeting with the North Korean leader, Kim Jong Un. Whether this latest move will lead to a new meeting with Putin is yet to be seen, however.

Writing on Truth Social, Trump said he was ordering the American boats to “the appropriate regions” due to what he called “the highly provocative statements of the Former President of Russia” and noted Medvedev’s status as a deputy chair of the Russian national security council.
