US President Donald Trump has issued a stern warning to Moscow, giving Russia a 50-day ultimatum to end its ongoing war in Ukraine or face a new round of crushing economic sanctions.
Speaking from the White House during a meeting with NATO Secretary General Mark Rutte, Trump made clear that the United States’ patience with Russian President Vladimir Putin is wearing thin.
“We’re very, very unhappy” with Russia, Trump said on Monday, warning of “very severe tariffs” if Moscow does not reach a peace deal within the next 50 days. These punitive measures, which he described as “secondary tariffs,” would target not only Russia but also nations and companies still engaged in trade with it. The aim, he explained, is to further isolate and economically strangle Moscow, which is already burdened by extensive Western sanctions imposed since the onset of the conflict.
The US leader used the occasion to announce a new strategic arms agreement with NATO. Under the plan, NATO would purchase American-made weaponry—including the advanced Patriot air defense systems—and channel them directly to the Ukrainian front. “This is billions of dollars worth of military equipment… going to NATO… and that’s going to be quickly distributed to the battlefield,” Trump said.
Rutte, who previously served as the Dutch prime minister before assuming leadership of the military alliance, added that Ukraine would be receiving “massive numbers” of weapons in the coming days. He said the joint NATO-US defense procurement deal is designed to significantly bolster Kyiv’s defenses against the intensifying Russian assault.
The announcement marks a shift in Trump’s approach toward Russia. When he resumed office in January for a second term, Trump had prioritized diplomacy with Putin and even pledged to end the war within 24 hours. His administration’s early efforts, however, stirred alarm in Kyiv, especially after a frosty February meeting at the White House where Ukrainian President Volodymyr Zelensky faced harsh criticism from Trump and his inner circle.
But Trump’s tone has notably hardened. On Monday, he commented on the Russian leader, stating, “I don’t want to say he’s an assassin, but he’s a tough guy.” The comment follows weeks of increased Russian bombardment across Ukraine, despite earlier American diplomatic overtures.
The US president had hinted last week at a major announcement on Russia, which materialized into Sunday’s revelation that Patriot air defense systems would soon be deployed to Ukraine. This development reverses an earlier stance by Washington, which had paused certain weapons deliveries earlier in July.
Marking another pivot, Trump dispatched his special envoy, Keith Kellogg to Kyiv. Following talks with Ukrainian officials, President Zelensky described the visit as “productive,” emphasizing joint efforts on air defense, weapons production, and cross-European cooperation. He also publicly thanked Trump for “important signals of support and the positive decisions for both our countries.”
Ukrainian frontline troops echoed Zelensky’s sentiment. A soldier known by his call sign “Grizzly,” stationed in the embattled eastern region, welcomed the new US weapons. “Better late than never,” he told AFP. “Because while we are here defending the front line, our families are unprotected. Thanks to the Patriots they are giving us, our families will be safer.”
Despite the renewed Western backing, the battlefield situation remains grim. On Monday, Russian forces claimed to have captured additional territory in eastern Ukraine, seizing two villages—one in the Donetsk region and another in Zaporizhzhia. Meanwhile, Ukrainian authorities reported that three civilians were killed in fresh Russian attacks on the Kharkiv and Sumy regions.
Back in Kyiv, President Zelensky proposed a significant political change. He recommended Economy Minister Yulia Svyrydenko to take over as Prime Minister amid what he described as a pivotal period in the nation’s wartime governance. Svyrydenko, reacting on social media, acknowledged the weight of the moment, stating, “Ukraine is facing a crucial time.”
Moscow, for its part, has yet to officially respond to Trump’s threat of economic retaliation or the renewed arms pipeline to Ukraine. However, the Russian leadership has consistently condemned Western military aid as an escalation.
