US President Donald Trump took a significant step to escalate tensions with Russia. He ordered the deployment of two nuclear submarines in response to Medvedev's statements.

Medvedev warned that Trump is playing an 'ultimatum game' with Russia, suggesting this could lead to war. Trump described these statements as provocative.

In his social media statement, Trump emphasized that 'words matter and can lead to unintended consequences.' This situation could create new tensions in international relations.

These developments are being closely monitored worldwide. Trump's nuclear submarine move serves as a warning against Medvedev's statements.

These developments may further strain the already tense relations between the US and Russia. The nuclear capabilities of both countries remain a significant concern for international security.
