Steve Rosenberg: Russia is staying quiet on Trump's nuclear move

Amidst a social media disagreement between President Donald Trump and former Russian President Dmitry Medvedev, Trump's order to move two nuclear submarines closer to Russia has raised concerns about a potential US-Russia nuclear standoff. However, Russian news outlets have downplayed Trump's announcement, with commentators dismissing it as "meaningless blather" and suggesting Trump may not have actually given any orders. Despite speculation, there has been no official response from Russian authorities, indicating that Moscow is either evaluating the situation or choosing not to react at this time.
