U.S. President Donald Trump issued a stark ultimatum today, threatening to impose 100% tariffs on countries trading with Russia unless a peace agreement to end the war in Ukraine is reached within 50 days.

"We are very, very unhappy with them," Trump said about Russia during a White House press briefing alongside NATO Secretary General Mark Rutte, who is visiting Washington. "We will impose very severe tariffs if we don't reach a deal in 50 days," he emphasized.

In the Oval Office, Trump reiterated his stance, stating, "We will apply secondary tariffs if no agreement is reached in 50 days. It's very simple. And they will be 100%."

The president also announced that the U.S. has struck a deal to sell weapons to NATO members, with Rutte confirming that these nations would then transfer the equipment to Ukraine to replenish its depleted arsenals.

"Today, we reached an agreement: We will send them weapons, and they will pay for them," Trump told reporters.

The threat comes as some U.S. lawmakers push for even harsher secondary sanctions against Russia as the war drags on. Senator Lindsey Graham is spearheading legislation in the Senate that would grant Trump the authority to impose tariffs of up to 500% on any country aiding Russia.

Appearing on Face the Nation the previous day, Graham described the measure as "a real hammer at President Trump's disposal to end this war." The South Carolina Republican, one of Trump's closest allies in Congress, argued that while the U.S. has "given a lot to Ukraine—money, military aid," a new approach could involve "selling massive amounts of weapons to our European allies that could then benefit Ukraine."

Last week, Trump hinted at approving additional funding for Ukraine, though the source of such funds remains unclear.

When Trump won reelection last year, European leaders scrambled to strategize how to sustain U.S. weapons transfers to Ukraine under his administration, given his campaign promises to withdraw American support. Eight months later, the White House appears to have settled on an alternative: selling arms to NATO allies, who would then supply Kyiv—effectively outsourcing the military aid while maintaining pressure on Moscow.

The 50-day deadline now sets the clock ticking for a potential escalation in economic measures should diplomacy fail.
