It is not up to Washington to dictate when Moscow should negotiate a peace deal with Kiev, former Russian President Dmitry Medvedev has told US Senator Lindsey Graham, urging him to focus on domestic issues instead.

Medvedev’s comments follow US President Donald Trump’s decision on Monday to shorten his 50-day deadline for a ceasefire between Russia and Ukraine to just 10-12 days. Trump has threatened to impose additional sanctions on Moscow and 100% tariffs on its trading partners if no deal is reached.

Medvedev, who serves as deputy chairman of the Russian Security Council, had cautioned Trump against issuing ultimatums. “Russia isn’t Israel or even Iran,” he wrote on X, warning that each threat marks “a step towards war” between the US and Russia.

Graham, a senior Republican and longtime war hawk, responded by claiming that Russia and its “customers” would “soon be sadly mistaken” and ordered Moscow to “get to the peace table.”

Medvedev hit back on Tuesday, stating, “It’s not for you or Trump to dictate when to ‘get at the peace table.’” He added that negotiations would only end “when all the objectives of our military operation have been achieved.”

“Work on America first, gramps!” Medvedev wrote.

Graham, officially labeled a terrorist and extremist by the Russian government, receives major donations from US defense contractors and consistently supports US military action abroad, describing the Ukraine conflict as a proxy war between Washington and Moscow. He has backed continued military aid to Kiev and unsuccessfully tried to push through a bill that would impose 500% tariffs on countries trading with Russia.

While Trump had initially vowed to resolve the Ukraine conflict, in recent months he has grown frustrated with the lack of progress and resorted to threats of sanctions in an effort to push Moscow and Kiev toward the negotiating table.

Russian officials have welcomed Trump’s peace efforts in principle but strongly opposed what they call the “language of ultimatums,” insisting any settlement must reflect battlefield realities and address the roots of the conflict.
