Gina Haspel, President Trump’s pick to lead the CIA, is good at her job because she cultivates alliances and counters adversaries.

That’s the story of Haspel’s 33-year career as a a CIA operations officer, which has seen her serve as the agency’s chief of station (the U.S. intelligence community’s top officer in embassies abroad) on four separate occasions. This includes two stints as the CIA’s station chief in London; once from 2008-2011 and again from 2014-2017.
