THE CLOCK IS TICKING: The countdown to a military strike on Syria is underway, and the only question seems to be whether the U.S. will act alone — as it did a year ago — or in concert with allies Britain and France. British media is reporting that Prime Minister Theresa May is under heavy pressure to join the U.S., perhaps by contributing Tomahawk cruise missiles from one of its Astute- or Trafalgar-class submarines.

President Trump spoke to both May and French President Emmanuel Macron Sunday, the day after the suspected chemical weapons attack in Douma, but before he had received military options from the Pentagon. The Times of London reports members of May’s government are warning that Britain risks losing influence in Washington and Paris if it turns down Trump’s request to join a retaliatory strike. “President Macron of France was said by Whitehall sources to be ‘egging on’ Mr. Trump,” the paper reports this morning. “They acknowledged that Downing Street had been left embarrassed as Mrs. May was still waiting to speak to Mr. Trump last night.”
