I believe that when the U.S. envoy was sent to Ukraine and negotiations were rejected during the war, it was a losing proposition for Ukraine and a one-sided deal favoring the United States. The likely agreement would have required Ukraine to repay the U.S. for previously supplied weapons by granting rights to its rare earth minerals.
Trump’s announcement of a swift resolution suggests that, at best, he secured the right of first refusal on these minerals, likely at prevailing market prices rather than any significant strategic advantage.
