In his zigzagging approach to ending the war in Ukraine, President Trump has shifted his frustration — for now — from Ukraine’s leader to Vladimir Putin.

The text of the agreement, made public by Ukraine’s government, made no mention of the security guarantees that Kyiv had long sought.

The announcement that the deal had been signed came after months of fraught negotiations.

The deal is intended to give the U.S. access to proceeds from Ukraine’s reserves of rare earth minerals.

There was no immediate comment from Ukraine about the unexpected announcement.

With uncertainty looming over cease-fire talks and U.S. support, the Ukrainian military is relying more than ever on domestically produced drones.
