Tens of thousands of North Koreans marched in anti-U.S. rallies over the weekend, pledging “merciless” revenge against “U.S. imperialists,” as the country marked the 73rd anniversary of the start of the Korean War. While the 1950-53 conflict was triggered by a North Korean surprise attack, the demonstrators mobilized in Pyongyang promoted their government’s version of events and accused the United States of provoking the war and leaving Koreans with “wounds … that can never be healed.”
