He was the American president who had restored and then expanded NATO, the world’s biggest military alliance, saving it from his predecessor’s threats to withdraw from it. He organized the West to push back against President Vladimir V. Putin of Russia, and in so doing deterred Moscow from direct attacks on European nations beyond Ukraine’s borders. And he became the architect of a new American plan to contain China, though he never calls it that: cutting off sophisticated technology to Beijing while pouring billions of federal dollars into producing advanced chips at home.

But Mr. Biden’s defense of his record came too late, after the shocking debate performance that led to his withdrawal from the race on Sunday. And now it will fall to a different nominee — likely but not certainly Vice President Kamala Harris — to defend that record from a radically different interpretation of the past four years promoted by former President Donald J.
