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.

WASHINGTON (AP) — In a warning to Russia, President Donald Trump said Friday he’s ordering the repositioning of two U.S. nuclear submarines “based on the highly provocative statements” of the country’s former president, Dmitry Medvedev, who has raised the prospect of war online.
