Former FBI director James Comey’s testimony to the Senate Intelligence Committee dominated the news this week, even before it happened. The Islamic State says it was behind attacks in Iran after claiming responsibility for an attack in London. President Trump picked a fight with London’s mayor just before Britain’s snap election. And Qatar’s neighbors in the Gulf turn unexpectedly hostile.
