United States President Donald Trump has confirmed that two American nuclear submarines are moving closer to Russian waters, escalating tensions between the two countries. The move follows a heated exchange with former Russian president Dmitry Medvedev, who referenced Russia's nuclear capabilities and warned that further ultimatums could lead to war. Trump stated that the deployment is a response to provocative statements from Russian officials and emphasized the need to protect American interests. The White House and Pentagon have declined to comment, while Russian officials seek clarity on the situation. The standoff comes after a deadly Russian airstrike on Kyiv and as Trump threatens severe sanctions if Russia does not agree to a ceasefire in Ukraine.
