During President Trump’s first term, Ukraine worried that Mr. Trump might
recognize Russian control over Crimea, the Ukrainian peninsula Moscow forcibly seized in early 2014.

As a candidate, Mr. Trump had said he would “take a look” at the matter, even though the Obama administration and America’s Western allies had rejected Russia’s annexation of the strategic territory. Mr. Trump even mused that “the people of Crimea, from what I’ve heard, would rather be with Russia.”

But Mr. Trump never followed through and even doubled down against Moscow. In July 2018, Secretary of State Mike Pompeo issued an official “Crimea Declaration” pledging that the nonrecognition policy would remain “until Ukraine’s territorial integrity is restored.”

Now, in his effort to negotiate an end to the war between Russia and Ukraine, Mr. Trump is prepared to walk away from that declaration — and more than a decade of American policy.
