With the anniversary of the U.S. drone strike that killed a top Iranian general approaching, there remains a "heightened risk" of an Iranian threat to American interests in the Middle East, the top U.S. general in the Middle East told ABC News in an interview. But Gen. Kenneth "Frank" McKenzie also downplayed that a conflict between the U.S. and Iran is more likely.
McKenzie made his comments a day after the U.S. Navy gave the rare acknowledgement that a U.S. submarine had entered the Persian Gulf, a move widely seen as sending a message to Iran.
