US President Donald Trump’s weekend was marked by heated rhetoric on foreign policy, as he issued a stark warning to Iran and expressed frustration with Russian President Vladimir Putin over the ongoing war in Ukraine.

During an early morning phone interview with NBC’s Kristen Welker, Trump reportedly said he was "angry" and "frustrated" with Putin’s recent remarks about Ukrainian President Volodymyr Zelensky. The Russian leader had suggested that Ukraine should explore alternative leadership as part of a potential peace agreement—a proposition Trump swiftly rejected as counterproductive.

“If Russia and I can’t strike a deal to end the bloodshed in Ukraine, and if I determine that Russia is at fault… I will impose secondary tariffs on all oil exports from Russia,” Welker quoted Trump as saying.

Trump, who has previously called Zelensky a "dictator," has had a strained relationship with the Ukrainian leader. Tensions were evident during Zelensky’s recent visit to Washington, where Trump criticized Ukraine’s wartime governance.

Despite his grievances with Putin, Trump maintained that he still had a "good relationship" with the Russian president but insisted that his frustration would ease if Putin made "the right choices" regarding Ukraine.

So far, diplomatic efforts by the Trump administration to negotiate a ceasefire in Ukraine have not yielded results. Russia recently dismissed a U.S.-supported proposal for a 30-day ceasefire and instead intensified military operations in northeastern Ukraine.

Trump’s proposed secondary tariffs would apply to nations purchasing Russian oil, potentially impacting major importers like China and India, making it harder for Moscow to finance its war effort.

Iran Receives a Military Warning

Alongside his comments on Russia, Trump also issued a stern warning to Iran, stating that military action could be imminent if Tehran refuses to engage in fresh nuclear negotiations.

“If they don’t agree to a deal, there will be bombings—bombings like they’ve never seen before,” Trump reportedly told NBC.

The U.S. had withdrawn from the 2015 nuclear accord during Trump’s first term, and diplomatic attempts to renegotiate have been largely unsuccessful. While Trump signaled that his administration remains open to discussions, he emphasized that Iran must commit to nuclear restrictions.

Responding to Trump’s remarks, Iran’s newly elected President Masoud Pezeshkian acknowledged ongoing indirect negotiations through Oman but rejected direct talks with Washington.

“Our supreme leader has stated that indirect discussions can continue. We do not shy away from negotiations, but their past unfaithfulness has created obstacles. They must prove they can be trusted in decision-making, and we hope this can be achieved,” Pezeshkian was quoted as saying by AFP.
