Medvedev was responding to a post by Trump on Truth Social hours earlier, in which the US president described him as a “failed” former leader and warned him to “watch his words,” adding that Medvedev was “entering very dangerous territory.”

“If some words from the former president of Russia trigger such a nervous reaction from the high-and-mighty president of the United States, then Russia is doing everything right and will continue to proceed along its own path,” Medvedev, who currently serves as deputy chairman of Russia’s Security Council, wrote on social media.

He also ridiculed Trump’s claim that the Russian and Indian economies were “dead” and going “down together” due to lack of cooperation with the US.

Medvedev had earlier dismissed Trump’s demands for Moscow to swiftly end its military campaign against Ukraine, calling the threats of secondary sanctions against Russian energy customers “theatrical” and ineffective. Medvedev insisted that such ultimatums will not prevent Russia from pursuing its national security goals and merely make Trump appear similar to his predecessor, Joe Biden.

Trump previously criticized the BRICS group of nations, which includes Brazil, Russia, India, China, and several other states pursuing a new multipolar world order. The US president claimed proposed tariffs on countries doing business with BRICS members could cripple the organization.

Trump’s statement regarding India and Medvedev followed New Delhi’s refusal to accommodate US demands on trade.

Medvedev, now serving as deputy chair of Russia’s Security Council, had earlier dismissed the notion that Trump, or any other US official, could dictate Moscow’s stance on the Ukraine conflict. His comments came in response to American calls for Russia to negotiate peace or face tougher sanctions.

Trump fired back on Wednesday in a post on Truth Social, in which he vented frustration over resistance from Russia and India to his international trade agenda. He claimed both countries had “dead economies,” before singling out Medvedev.

“Tell Medvedev, the failed former President of Russia, who thinks he’s still President, to watch his words. He’s entering very dangerous territory!” Trump wrote.

Medvedev responded, saying the “nervous” reaction by the American leader simply proved that Russia was right in its policy choices and should maintain its course.

Earlier this week, Medvedev responded to remarks by US Senator Lindsey Graham, who warned Russia to comply with Trump’s demands for swift peace talks with Ukraine or face consequences.

Medvedev retorted that “it’s not for you or Trump to dictate when to ‘get at the peace table.’”

Medvedev has criticized what he described as Trump’s “theatrical” ultimatums, warning that such pressure tactics only increase the risk of a direct conflict between the two nuclear powers. “Don’t go down the Sleepy Joe road!” he said, referencing Trump’s mocking nickname for former President Joe Biden.

Russia continues to assert that it will meet all of its military objectives in the Ukraine conflict, whether by force or diplomacy. Officials in Moscow say a negotiated resolution is preferable but currently unfeasible due to what they describe as Kiev’s unreasonable positions and unwillingness to engage in good-faith talks.
