Kremlin officials dismissed US President Donald Trump’s 50-day ultimatum for a Ukraine ceasefire while Russian President Vladimir Putin remained silent on the demands, the Institute for the Study of War reported on 15 July, citing Russian Telegram channels, controlled by Kremlin.

During a 14 July Oval Office meeting with NATO Secretary General Mark Rutte, Trump threatened “severe tariffs” if Russia doesn’t make peace within 50 days but declined to specify how far he would escalate if Putin increases pressure. Trump also called Putin “a tough guy” and said he was “angry” at the Russian leader for not being “nice.”

Russian Deputy Foreign Minister Sergei Ryabkov told TASS on 15 July, according to the ISW, that Russia views “especially ultimatums” as “unacceptable.” Ryabkov said Russia’s position is “unshakable” and Moscow will continue pursuing war aims militarily if the US and NATO ignore Russian demands.

Security Council Deputy Chairperson Dmitry Medvedev posted that “Russia didn’t care” about Trump’s “ultimatum.” Foreign Minister Sergei Lavrov expressed confidence Russia will cope with US tariffs, as Moscow is already “coping” with prior sanctions.

Putin has yet to officially respond and is likely attempting to identify narratives that could convince Trump not to follow through with tariffs in September 2025, according to ISW.

Trump announces $10 billion Ukraine aid

Trump announced a $10 billion military package for Ukraine including Patriot missiles and air defense weapons. NATO countries will purchase the weapons from the US and transfer them to Ukraine.

The package may authorize Ukraine to use 18 long-range ATACMS missiles at full 300-kilometer range, enabling strikes on Russian military bases and supply depots previously out of reach.

Trump considered sending Tomahawk cruise missiles – the same weapons used against Iranian targets last month. “If fired from Ukraine, these could hit Moscow and St. Petersburg,” the Washington Post reported. Tomahawks aren’t included in current deliveries but could be deployed later.

Trump’s announcement followed his disappointment with Putin’s unwillingness to pursue ceasefire talks. Putin told Trump during their 3 July call that Moscow plans to escalate operations in eastern Ukraine within 60 days, “securing the full administrative borders of occupied Ukrainian oblasts.”

“Trump is really pissed at Putin. His announcement tomorrow is going to be very aggressive,” Sen. Lindsey Graham told Axios.
