U.S. Secretary of State Antony Blinken has kicked off his first month in the job with a blaze of diplomacy.

As part of his effort to re-energize American alliances frayed by the Donald Trump years, Blinken has spoken with dozens of his counterparts around the world and joined gatherings of Asian and European leaders ¡ª all without ever leaving his seventh-floor office at the State Department.

As the world struggles to get the coronavirus pandemic under control, most diplomatic travel remains postponed. In ordinary times, Blinken would have hosted a stream of visitors and logged thousands of air miles by now; instead, he has relied on the telephone and video screens, much like Zoom-dependent workers everywhere.
