Trump Sees ‘Good Signals’ on Russia-Ukraine Cease-Fire. Zelensky Does Not.

President Trump said Thursday he saw “good signals” toward finalizing a 30-day cease-fire agreement between Russia and Ukraine, as U.S. officials visiting Moscow were expected to meet with President Vladimir V. Putin of Russia.

The remarks, delivered in the Oval Office while meeting with NATO Secretary General Mark Rutte, came as Mr. Putin made clear he was in no hurry for a cease-fire, laying out numerous conditions before he could agree to a truce.

“It doesn’t mean anything until we hear what the final outcome is, but they have very serious discussions going on right now with President Putin and others, and hopefully they all want to end this nightmare,” Mr. Trump said of the meetings his Middle East envoy, Steve Witkoff, was having in Russia. “It’s a nightmare. It’s a horrible thing.”

Mr. Trump said he hoped to speak to Mr. Putin soon. He also said the U.S. had discussed with Ukraine possible concessions as part of a peace agreement.

“We’ve been discussing with Ukraine land and pieces of land that would be kept and lost, and all of the other elements of a final agreement,” Mr. Trump said.

He added: “A lot of the details of a final agreement have actually been discussed.”

President Volodymyr Zelensky of Ukraine struck a pessimistic tone in his evening address to Ukrainians on Thursday. Mr. Putin’s response to the cease-fire proposal, he said, was “very predictable.” Mr. Putin, he said, set so many preconditions “that nothing will work out at all, or that it will not work out for as long as possible.”

Despite Mr. Trump’s years of complaints about NATO, an organization from which he has repeatedly threatened to withdraw, the meeting with Mr. Rutte, a former Dutch prime minister, proceeded amicably as the two leaders discussed areas of cooperation.

Mr. Trump commended Mr. Rutte for “doing a fantastic job” while Mr. Rutte heaped praise on Mr. Trump, crediting him with revitalizing the organization by pushing countries to contribute more military spending.

“I really want to work together with you in the run-up to The Hague summit to make sure that we will have a NATO which is really reinvigorated under your leadership, and we are getting there,” Mr. Rutte said, referencing this summer’s meeting in the Netherlands.

Many American presidents have complained that other European allies do not spend enough on defense, relying instead on American protection, but Mr. Trump has escalated the rhetoric to a new level, suggesting the U.S. may not fulfill its mutual defense commitment for countries that have not contributed enough.

Mr. Trump’s more conciliatory approach to Russia and his sweeping tariffs on the European Union have also divided the alliance and its member states, some of which are starting to explore a future that does not depend so heavily on the United States.

Mr. Rutte, seeking to avoid the kind of confrontation that blew up Mr. Trump’s meeting with Mr. Zelensky in early March, complimented the U.S. president and tried to steer away from conflict — at least in front of news cameras.

When Mr. Trump was asked about his efforts to annex Greenland — a territory controlled by Denmark, a NATO member — the president noted that Mr. Rutte “could be instrumental” in making that happen.

“We have to do it,” he said. “We really need it for national security.”

Mr. Rutte deflected the question of the United States taking Greenland, saying he did not want to “drag NATO into that.” Instead, he pivoted to agreeing with Mr. Trump that Russia and China posed threats to the Arctic region.
