So what do Ukrainian strikes on Iranian cargo -- or Russian ships -- in the Caspian mean for the two wars? "I suspect these types of operations will make shipping between Russia and Iran across the Caspian increasingly difficult," he said. Ukraine had "achieved very strong results with long range strikes in the Caspian Sea, including vessels used in military cargo shipments involving Iran," Ukraine's president, Volodymyr Zelenskyy, said in a post to Telegram. "I also doubt it's a coincidence that these strikes against Iranian shipping occurred just days before" Zelenskyy's White House meetings.
