One of the legacies of Vladimir Putin will be that he made the enduring riddle of Russia far less ambiguous — one aspect of it, anyway. In a foreign policy announcement last week that surprised no one, Mr. Putin said that “the Russian Federation intends to eliminate the worldwide dominance of the United States and other unfriendly countries.” For Moscow, hostile nations include those that imposed sanctions on Russia as a response to Mr. Putin’s war on Ukraine. They do not include NATO member Turkey.
