After three days of intense negotiations, the Trump administration, Ukraine and Russia agreed to a limited ceasefire in which the key details, including what was covered and how it will start, were disputed by the warring sides.

It remains unclear if the commitments to stop attacks and ensure safe shipping in the Black Sea, which came with many caveats, would happen soon.

That helps explain why President Donald Trump’s promise to end the war between Russia and Ukraine (within a day, as he used to say) is proving difficult. His officials say they have achieved “epic” results.
