Trump calls for help in the Middle East. Allies aren't answering

U.S. President Donald Trump is calling for countries including China and his NATO allies to send ships and help reopen the Strait of Hormuz, a key artery for the world's oil that's been choked by Iran — but neither friend nor foe has agreed to do so. Retired lieutenant-general Andrew Leslie, a former Canadian Army commander, says 'the level of strategic incoherence coming out of the White House, and specifically the president of the United States, is unsupportable.'
