US President Donald Trump has called Russia's nuclear-powered Burevestnik cruise missile test "inappropriate" and advised Russian President Vladimir Putin to focus on ending the conflict with Ukraine. Donald Trump also highlighted the US' nuclear capabilities, stating that they have a nuclear submarine.

"They know we have a nuclear submarine, the greatest in the world, right off their shores. So, I mean, it doesn't have to go 8,000 miles. And they're not playing games with us. We're not playing games with them either. We test missiles all the time," Donald Trump said while interacting with reporters on Air Force One.
